Source ⁄ description: The single-stranded DNA-binding protein 1
(SSBP1) is a transcription factor involved in the regulation of
the thyroid stimulating hormone receptor (TSHR). It belongs to
a family of SSBPs that interact with RNA and with the pro-
moter of retroviruses, and have an important role in RNA
processing. The SSBP1 maps to human chromosome 7 (HSA7).
Polymerase chain reaction (PCR) primers flanking the third and
fourth introns of the ovine SSBP1 gene were designed using the
targeted intronic polymorphic sequence identification (TIPS)
procedure1. The PCR products were tested for similarity with
non-redundant (nr) sequences in GenBank (http://www.ncbi.
nlm.nih.gov/) using the BLASTN algorithm2. The coding
sequences flanking the introns were unequivocally aligned
to their homologous sequences in the human SSBP1 gene
(GenBank accession number NM_003143). The ovine SSBP1
sequence was deposited with the GenBank nucleotide sequence
database under accession number AY115486. A repeated se-
quence (T)6, identified within the third intron at position 469 in
AY115486, showed variation in different individuals. This
microsatellite was designated as OARCDT7. We designed PCR
primers flanking OARCDT7 and used it to map SSBP1 in sheep.
Primer sequences: OARCDT7 – Forward primer: 5¢- GAGCTTA
ATGCTTGTTTTGTGG-3¢OARCDT7 – Reverse primer: 5¢- CAGGAAACAAGTGTGAGG-
AGC-3¢
Analysis ⁄ Mendelian inheritance: The OARCDT7 was amplified by
PCR and analysed by denaturing polyacrylamide gel electro-
phoresis. Two alleles were identified and their codominant
segregation was verified in the AgResearch International
Mapping Flock (IMF), comprising nine three-generation families
with a total of 127 animals3.
Chromosomal location: The OARCDT7 was mapped against the
markers on the latest version of the sheep framework map4.
Multipoint linkage analysis of the IMF pedigrees using CRI-
MAP5 localized OARCDT7 in the distal part of ovine chromo-
some 4, between markers BM2023 and CSRD219, with its
most likely position at BM2023. Two-point likelihood of odds
(LOD) scores and recombination fractions for these loci are
shown in Table 1.

Source ⁄ description: In mammals, two types of T cells can be
distinguished by the surface expression of either an ab or cdT-cell receptor1. The ability of cd T cells to recognize non-
peptidic molecules supports the notion that they are associated
with innate immunity2. In striking contrast to humans and
mice, the lymphoid systems of artiodactyls contain a large
number of cd T cells3. However, the biological significance of
these differences between species remains unknown.
The ovine T-cell receptor c chains are encoded by five con-
stant genes4. Two of them (TCRGC1 and TCRGC2) have been
shown to map separately in two different regions of chromo-
some 4 (OAR4) by in situ hybridization5. However, no poly-
merase chain reaction (PCR)-based molecular marker has been
developed for these genes until now. In an attempt to find
markers for the ovine T-cell receptor c genes we searched the
GenBank database and identified one microsatellite sequence in
the TCRGC1 and two in the TCRGC4 genes (GenBank (http://
www.ncbi.nlm.nih.gov/) accession numbers AF047015 and
AF241308, respectively). We designed PCR primers flanking
these microsatellites and verified that they were polymorphic in
sheep. A linkage map for TCRGC1 and TCRGC4 is reported,
showing that these loci map to different areas on OAR4. In
contrast, the human T-cell receptor c genes are clustered in the

Analysis: The microsatellites were amplified by PCR and ana-
lysed by denaturing polyacrylamide gel electrophoresis.
Genomic DNA 16 ng was amplified in a 4-ll reaction volume
consisting of 67 mM Tris–HCl (pH 8.8), 16.6 mM (NH4)2SO4,
0.2 mg ⁄ ml gelatine, 0.45% Triton X-100, 1.5 mM MgCl2,
100 lM dNTPs, 2.7 pmol of both the forward and reverse
primers, 0.1 U Amplitaq DNA polymerase (Applied Biosystems,
Melbourne, Australia), 0.22 lg of TaqStart Antibody (Clontech,
Palo Alto, CA, USA) and 0.4 lCi a 33P d-ATP (GeneWorks,
Adelaide, Australia). Reactions were set up in a 96-well plate
and run on a DNA thermal cycler (PTC-100, MJ Research Inc,
Waltham, MA, USA), using the following conditions: 1 cycle of
denaturation at 95 �C (2 min, 50 s); 30 cycles of denaturation
at 95 �C (10 s), annealing at the temperature given in Table 1
(30 s), extension at 72 �C (30 s); and 1 cycle of extension
72 �C (2.5 min).
Polymorphism ⁄ Mendelian inheritance: The number of alleles and
the polymorphic information content of each microsatellite
were determined using a panel of unrelated sheep from 10
different breeds (Merino, Border Leicester, Suffolk, Romney,
Karakul, Finnish Landrace, Poll Dorset, Dorset, Texel and
Carpet Master) (Table 1). Codominant segregation of the alleles
was verified in the AgResearch International Mapping Flock
(IMF), comprising nine three-generation families with a total of
127 animals6.

Brief notes 469
Chromosomal location: The TCRGC1 and TCRGC4 were mapped
against the markers on the latest version of the sheep
framework map7. In the case of TCRGC4, alleles for the two
microsatellites were combined to obtain the individual hapl-
otypes. Multipoint linkage analysis of the IMF pedigrees using
CRIMAP7 localized these loci to different regions on OAR4.
The most likely position for TCRGC1 was estimated to be be-
tween OarCP26 and OarHH35, whereas TCRGC4 mapped in a
relatively proximal location, between EPCDV006 and RM67.
Two-point likelihood of odds (LOD) scores and recombination
fractions for these loci are shown in Table 2 and the linkage
map of OAR4 in Fig. 1. The two genes are approximately
40 cM apart.

Source ⁄ description: Chemokines are a family of small pro-
inflammatory cytokines involved in chemotaxis and the acti-
vation of specific subsets of leucocytes. They play a key role in
mobilizing inflammatory cells in response to infections1. Inter-
leukin-8 (IL-8) belongs to the alpha chemokine family. Porcine
IL-8 complementary DNA (cDNA) has been sequenced2 and
assigned to the porcine chromosome 8 linkage map by
restriction fragment length polimorphism (RFLP) analysis3. We
have subsequently performed analyses of the genomic porcine
IL-8 gene. A primer set (IL8ex2F and IL8ex3R) was designed
from the porcine IL-8 cDNA sequence2 to amplify the genomic
IL-8 fragment and then used to screen a porcine BAC library4.
Restriction fragments from a clone containing the IL-8 gene
were subcloned. The resulting sequences were aligned and
compared with genomic sequences of the human and canine
IL-8 genes5,6.
Genomic structure: About 3.9 kb of genomic sequence for por-
cine IL-8 gene was determined (GenBank accession number
ABO57440). The coding region of the genomic IL-8 gene
sequence was completely identical with the corresponding
region of the previously reported porcine cDNA2. The structure
of the IL-8 gene consisted of four exons (exon 1: 147 bp, exon
2: 136 bp; exon 3: 84 bp and exon 4: 1120 bp), and three
introns (intron 1: 1022 bp; intron 2: 288 bp; and intron 3:
428 bp), with 410 and 272 bp of 5¢ and 3¢ flanking regions,
respectively. The GC- and TATA- box like sequences were found
116 bp upstream of the initiation codon (Fig. 1). The promoter
sequences, the exon–intron organization and size of exons and
introns were highly conserved among pig, human and canine.
A microsatellite with a (TA)18 repeat sequence was identified in
intron 1 of porcine IL-8, but not found in either the human or
canine sequences. A primer set (SJ108F and SJ108R) was
designed to amplify the microsatellite (SJ108) for subsequent
analyses.

Allele frequency: Allele frequencies of SJ108 were determined
for 53 unrelated pigs from five breeds. Polymorphisms con-
sisting of eight alleles between 164 and 182 bp were being
widely distributed in the breeds (Table 1).
Mendelian inheritance: Codominant Mendelian segregation of
SJ108 was observed in a Meishan · Gottingen miniature pig
experimental family7.
Chromosomal location: Using genotype data from the experi-
mental family the microsatellite marker, SJ108, within the IL8
gene was mapped on porcine chromosome 8 by linkage analysis
(Table 2). These results confirmed the previous mapping study3.

Source ⁄ description of primers: A cDNA clone containing the full
coding region of the porcine alpha-fetoprotein (AFP) was iso-
lated (GenBank accession no. AF517770) from the �Meat
Animal Research Center (MARC) 2PIG� expressed sequence tag
primary library by iterative screening1 using a forward (AFP
F1) and a reverse (AFP R2) primer for polymerase chain
reaction (PCR) amplification. AFP F1 was designed from the
horse AFP sequence (GenBank accession no. U28947), and
AFP R2 corresponds to bases 841–822 of the porcine cDNA
sequence. After alignment of the sequence with the human AFP
gene sequence, primers to amplify across putative intron 10
were designed based on the porcine cDNA sequence. The for-
ward (AFP exon 10 F1) and reverse (AFP exon 11 R1) primers
correspond to bases 1246–1264 and 1442–1424 of the por-
cine AFP cDNA (GenBank accession no. AF517770). Based on
the human genomic sequence, this intron was expected to be
approximately 482 bp. Agarose gel electrophoresis and
sequencing of the PCR amplicons of porcine genomic DNA
indicated that the corresponding region of the pig gene was
565 bp. The PCR product was confirmed by sequencing
(GenBank accession no. AY120900).

Taq polymerase. Amplification was performed under the fol-
lowing PCR conditions; 2 min at 94 �C; 45 cycles of 30 s at
94 �C, annealing for 1 min at 65 �C, 1.5 min at 72 �C; and
a final extension of 5 min at 72 �C. The amplified genomic
DNA of eight parents (seven F1 sows and one white com-
posite boar) from the MARC swine reference population2
were bidirectionally sequenced and evaluated for polymor-
phisms3.
Polymorphism and chromosomal location: A C ⁄ T single nucleo-
tide polymorphism was detected in intron 10 (GenBank
accession no. AY120900), position 476 from the exon ⁄ intron
boundary. This polymorphism was heterozygous in six of the
seven F1 sows. An assay was designed to genotype this poly-
morphism using primer extension with the AFP probe primer
and analyte detection on a MALDI-TOF mass spectrometer4
(Sequenom Inc., San Diego, CA, USA). This marker generated
68 informative meioses in the MARC swine reference popula-
tion. The AFP gene was mapped to chromosome 8 position
60.4 cM, which is the same position as marker S0017 on the
current MARC swine chromosome 8 linkage map (http://
www.marc.usda.gov/) using CRI-MAP. The most significant
two-point linkage detected was with S0017 (LOD ¼ 18.36) at
0 recombination. The location of the porcine AFP gene is
within the 95% confidence interval of the uterine capacity
quantitative trait locus (QTL) on chromosome 85. The AFP
gene in human is located on chromosome 4q11-q13, which
shares homology with swine chromosome 8. AFP is the pre-
dominant protein in foetal plasma during early gestation (days
15–30) in the pig6, which may be important for foetal devel-
opment.

Source ⁄ description: Diacylglycerol acyltransferase (DGAT1) is a
microsomal enzyme that catalyses the final and only committed
step in formation of triglycerides, which are the major form of
stored energy in eukaryotes1. DGAT1-deficient mice are viable,
lean, able to synthesize triglycerides, and resistant to diet-in-
duced obesity2. DGAT1-deficient females also have a complete
absence of milk production and a substitution in the bovine
DGAT1 gene has a major effect on milk yield and fat content3.
A full-length porcine DGAT1 complementary DNA (cDNA)
was identified from the MARC 2PIG normalized library4 and
sequenced (GenBank accession number AY093657). The
1935 bp cDNA contained 198 bp of 5¢-UTR, 1470 bp of coding
sequence and 261 bp of 3¢-UTR. Porcine DGAT1 cDNA has 83,
88 and 91% nucleotide identity in the coding region with
mouse, human and bovine cDNAs, respectively. Pig DGAT1
cDNA codes for a protein of 489 amino acids with 85, 86 and
92% identity to mouse, human and bovine proteins, respect-
ively.
The porcine DGAT1 gene was cloned by iterative polymerase
chain reaction (PCR) screening of a cosmid library5 using PCR
primers DGAT-F5 and DGAT-R8 (Table 1). Primers were
designed from porcine DGAT1 cDNA and used to sequence the
cosmid and amplify genomic DNA.
Gene organization: The genomic structure was identical to that
of the human and bovine genes with respect to intron size and
organization of the 17 exons6,3. A GT ⁄ poly(dG) repeat was
found immediately following (66 bp) the polyadenylation signal
and cleavage site. The complete DGAT1 gene was sequenced
except for about 700 bp of intron 1 (GenBank accession
number AY116586); however, enough flanking sequence was
obtained in order to amplify coding sequence of exons 1 and 2
from genomic DNA (Table 1).
PCR conditions: The PCR reactions were performed in 25 ll
using 100 ng of genomic DNA, 1XPCR buffer, 1.5 mM MgCl2,

submitted to GenBank and have been assigned the accession

0.200 mM dNTP, 0Æ8 lM each primer and 0.5 U Hotstar� Taq
(Qiagen Inc., Valencia, CA, USA). The PCR profile included
15 min at 94 �C; 35 cycles of 45 s at 94 �C, 45 s at 57 �C,
1–1.5 min at 72 �C; and a final 5 min extension at 72 �C in a
PTC-225 thermocycler (MJ Research Inc., Waterton, MA, USA).
Polymorphisms: Several single nucleotide polymorphisms (SNP)
were found in porcine DGAT1 using the MARC Swine Reference
Population, primarily in introns and non-coding regions
(Table 2). Silent SNPs were found in amino acids 173, 197,
245, 321 and 344. One SNP, an A or G polymorphism at
position 103 of intron 2 was used to map porcine DGAT1 in the
MARC swine mapping population. The A allele provided a
restriction site for AvaII and the PCR–restriction fragment
length polymorphism (RFLP) was amplified using primers
DGAT-Fi1 and DGAT-Ri2 primers (Table 1).
Chromosomal location ⁄ linkage: Linkage analysis placed DGAT1
on porcine chromosome 4, relative position 0 based on 85 in-
formative meioses. The most significant linkage detected was
with SW2404 (LOD ¼ 18.66, theta ¼ 0.0). Other genes
mapped on this arm of SSC4 include TG and MYC at 4p157,
EXT1 at 41 cM8 and DECR1 at 53 cM
9 with DGAT1 being the
most telomeric gene mapped.
Comments: Human DGAT1 maps to 8q24.3, and bi-directional
chromosome painting and comparative mapping10 have iden-
tified SSC4 to be syntenic with portions of human chromosomes
1 and 8. This chromosomal assignment is consistent with the
relative positions of TG, MYC and DECR1 on the comparative
map. Although DGAT1 does not map within the major quan-
titative trait loci (QTL) interval for backfat thickness or intra-
muscular fat in the pig, it does map within suggestive QTL
intervals for growth rate, intramuscular fat, and fatty acid
composition11–13.

Source ⁄ description of primers: Quinoid dihydropteridine reduc-
tase (QDPR) catalyzes the NADH-mediated reduction of
quinonoid dihydrobiopterin and is an essential component of
the pterin-dependent aromatic amino acid hydroxylating sys-
tems1. A cDNA clone containing the full coding region of the
porcine QDPR (GenBank accession no. AF526879) has been
isolated from the �Meat Animal Research Center (MARC) 2PIG�expressed sequence tag primary library2. Primers were designed
to amplify across the 3¢ untranslated region of the cDNA. The
forward (F3) and reverse (R1) primers correspond to bases
744–763 and 1118–1098 of the porcine QDPR cDNA. Agarose
gel electrophoresis and sequencing of the polymerase chain
reaction (PCR) amplicons of porcine genomic DNA indicated
that the size of this product was 375 bp as expected.

PCR conditions: Polymerase chain reactions were carried out in
a 25-ll volume containing 100 ng genomic DNA, 1.5 mM
MgCl2, 20 pmol of each primer, 100 lM dNTP, and 0.35 U Taq
polymerase. Amplification was performed under the following
PCR conditions; 2 min at 94 �C; 45 cycles of 30 s at 94 �C,
annealing for 1 min at 61 �C, 1 min at 72 �C; and a final
extension of 5 min at 72 �C. The amplified genomic DNA of
eight parents (seven F1 sows and one white composite boar)
from a subset of the MARC swine reference population3 were
bidirectionally sequenced and evaluated for polymorphisms4.
Polymorphism and chromosomal location: An A ⁄ G single nuc-
leotide polymorphism was detected at nucleotide 1075 in
AF526879. This polymorphism was heterozygous in five of the
seven F1 sows and two boars from the MARC swine reference
population3. An assay was designed to genotype this poly-
morphism using primer extension with analyte detection on a
MALDI-TOF mass spectrometer (Sequenom Inc., San Diego, CA,
USA)5. This marker generated 153 informative meioses in the
MARC swine reference population. The QDPR gene was map-
ped to chromosome 8 position 25.7 cM, which is the same
position as marker PEPS6 on the current MARC swine chro-
mosome 8 linkage map (http://www.marc.usda.gov/) using
CRI-MAP. The most significant two-point linkage detected was
with PEPS (LOD ¼ 29.50) at 0 recombination. The QDPR
gene in human is located on chromosome 4p15.31, which
shares homology with swine chromosome 8.

Description: Genetic linkage maps of some of the main cultured
fish species were constructed in recent years. Maps of tilapia1–3,
trout4 and catfish5 consist of hundreds of microsatellites and
amplification fragment length polymorphism DNA markers, but
only several genes.
Microsatellites DNA markers are short tandem repeats,
usually dinucleotide (CA)n, with unique flanking sequences,
providing primer binding sites for PCR amplification6. Micro-
satellites are highly abundant throughout the genome and
appear in coding and non-coding regions. Therefore, it is likely
that the flanking sequences can be part of a gene, which can be
identified by similarity searches against the GenBank sequence
database. This in silico data mining approach has already been
used to identify genes in mice7, cattle, pigs and chicken8. In this
study we utilized a similar approach to add nine anchored
genes to the current 14 genes in the tilapia3 map, and suggest
seven additional genes that can be anchored by mapping to
their matching microsatellites.
Methods: Microsatellites sequences were downloaded in FASTA
format from the GenBank database using the Entrez nucleotide
query webpage (http://www.ncbi.nlm.nih.gov/Entrez). The
search string used to retrieve the tilapia microsatellites was

(Oreochromis [organism] OR tilapia [organism]) AND (micro-
satellite [all fields] OR STS [all fields]). All repeats were masked
using RepeatMasker (http://ftp.genome.washington.edu/RM/
RepeatMasker.html). The masked sequences were queried
against the non-redundant (nr), expressed sequence tags (EST),
high throughput genomic sequences (HTGS) and genome sur-
vey sequence (GSS) databases of GenBank using Blastn and
Blastx searches. We used batched blast (http://zfish3.uoregon.
edu/blast_scripts/web_batch_blast.pl) for individual search of
each locus. The Blastn search was limited to at least 12 con-
secutive nucleotide alignment and minimum sum expect value
(E) of less than 0.0001 and the Blastx search was limited to at
least three consecutive amino acids alignment and E of less
than 0.01. Sequences meeting these criteria were reviewed in
order to eliminate matches resulting from vectors and primers
in unedited sequences. Any match of DNA or protein sequences
to human genes was followed by a Blat search of the human
sequence, against the sequence of the human genome draft
(http://genome.cse.ucsc.edu/index.html), to define the source
of similarity in the gene. The Fugu rubripes database (http://
fugu.hgmp.mrc.ac.uk/blast/) was consulted to confirm
sequence matches and compare the exon structure to obtain
further evidence for identification of a true gene. Matches for
uncharacterized proteins and hypothetical proteins were
excluded from the reported results.
Results and discussion: By comparing sequences of 312 tilapia
microsatellites to GenBank database, 16 known genes have
been localized (Table 1). Twelve genes have been found using
the Blastx and four by Blastn. Searching against the EST, GSS
and HTGS databases did not add known genes to those found in
the nr database. Eleven of the 16 sites were localized to the
same genes in two or more vertebrate species, thus supporting
the detection of the true genes.
In cases of uncertainty, where E-values were ‡0.001
(UNH735 and UNH872), the sequences were blasted against
the database of the Fugu genome project. The matching contigs
included similar genes to those found in GenBank. Blastn of
UNH735 against the Fugu database gave an E-value of 1e-04
with identity of 100% (25 ⁄ 25) and Blastx of UNH872 yielded
an E-value of 2e-08 with 100% identity (29 ⁄ 29). Further in-
dication that these matches were true was obtained from exact
compatibility of the exon–intron boundaries, which are con-
served among vertebrates9. Matched sequences, such as
UNH933, that corresponded to intronic sequence were
removed from this report. Sequences of coding regions are more
conserved than non-coding regions and thus are better pre-
dictors of genes in different species. Sequence similarity to an
intronic region might be due to identity in control region, a
pseudo gene or a false match.
This rapid in silico approach has added nine genes to the
tilapia linkage map, which contains only 14 genes. Seven more
genes matched unmapped microsatellies. The localized genes in
tilapia provide anchors for comparative mapping with other
vertebrates. In the future, with the increased effort of sequen-
cing the genomes of several animal species, more genes can be
mapped using this in silico method.

Source ⁄ description: Tyrosinase is an important gene in
the melanin pathway1 and is expressed in pigmented skin.
Primers, which amplify exon 1 of the tyrosinase gene (TYR),
were designed based on human sequence (GenBank M63235)
for use in several species. The amplified dog fragment
(AF473807) had a SNP (G ⁄ A) at nucleotide 175 from the
start of the coding sequence, based on alignment to the DNA
sequence for dog TYR exon 1 submitted by Tang to GenBank
(U42219), or 118 bp of the incomplete exon 1 sequence we
submitted. The SNP was responsible for a conservative amino
acid change (valine to isoleucine). Homozygotes of both alleles
were present in a set of Large Munsterlander dog families.
These dogs are black and white spotted, with or without small
spots called ticking and ⁄ or roan. No sequence differences were
detected in the ticked and non-ticked dogs which had more
white patches.
Primer sequences:
Forward: ATGCTCCTGGCTGTTTTGTACTGCCTG
Reverse: CTGCCAAGAGGAGAAGAATGATGC
Polymerase chain reaction (PCR) conditions: The PCR reaction of
15 ll contained 1 ll of DNA template (50–100 ng), 1.5 ll of
PCR buffer (Invitrogen, Burlington, ON, Canada), 0.6 ll of
50 mM MgCl2, 0.3 ll of 10 mM dNTP, 0.1 ll Taq polymerase
(5 U ⁄ ll, Gibco), 1 ll of each primer (10 pM ⁄ ll) and 9.5 ll
ddH2O. The reaction began with a 4-min step at 94 �C,
� 2002 International Society for Animal Genetics, Animal Genetics, 33, 468–485
Brief notes476
followed by 30 cycles of 30 s at 94 �C, 35 s at 56 �C, and
45 s at 72 �C, and finishing with a 4 min step at 72 �C.
Samples were digested with 1 ll of Rsa1 (10 U ⁄ ll) for 3 h at
37 �C.
Polymorphism: Polymerase chain reaction amplified a 819 bp
fragment. Digestion with Rsa1 yielded either a four-band pat-
tern (19, 68, 289 and 442 bp) for allele A, or a five-band
pattern (19, 68, 157, 286 and 289) for allele G. Heterozygotes
had the 19, 68, 156, 286, 289 and 442 bp bands. Bands were
resolved on a 2% gel, as the 156 and 442 bp bands were
enough to determine the allelic identity. Therefore, resolution
between the constant 289 bp band and the 286 band of the G
allele was not necessary.
Mendelian inheritance: Codominant inheritance was observed
within the three families tested for the SNP.
Chromosomal location: Chromosome painting studies2,3 indica-
ted that canine chromosome 21 was homologous with human
chromosome 11q21, where TYR has been mapped4. Microsat-
ellite FH2312 from syntenic group 25 and ZuBeCa21 from
DogMap linkage group 43 or CFA21 were genotyped on the
three families that segregated for the TYR polymorphism.
Microsatellite FH2312 was heterozygous in all three families.
No recombinant offspring was noted between the TYR SNP and
FH2312. A LOD score of 3.3 at 0 cM was found. FH2312 maps
at 0 cM on the Fred Hutchinson Cancer Research Center
(FHCRC) Dog Genome Project map of syntenic group 25, which
was recently assigned to CFA216. We also found evidence of
linkage between TYR and ZuBeCa21 of CFA21 on DogMap7
although the statistical support was weak (LOD ¼ 1.48,
0 cM).
Comment: A portion of this exon 1 tyrosinase sequence was
used in a phylogenetic study of placental mammals8.

Mapping data were placed in the INRA RH mapping database
(http://imprh.toulouse.inra.fr/). Map distances and two-point
LOD scores were provided by the INRA RH website. The posi-
tion of markers for which the two-point LOD score is less than 6
should be considered preliminary.
PCR conditions: Oligonucleotide primer-pairs for each locus
(Table 1) were optimized for PCR amplification by testing over a
range of annealing temperatures against porcine and hamster
genomic DNA to ensure porcine-specific amplification. The PCR
reactions (15 ll total volume) included 25 ng RH DNA,
1.5 mM MgCl2, 2.5 pmol each primer, 100 lM dNTP and
0.35 U Hotstar Taq polymerase (Qiagen, Valencia, CA, USA).
Amplifications were performed in an MJ Research thermal
cycler (Waltham, MA, USA) under the following reaction
conditions: 15 min at 94 �C; 30 cycles of 30 s at 94 �C, 30 s at
annealing temperature, 30 s at 72 �C and a final extension of
