Trasket Ball
Teams based on rows (adjustments will be made as needed)
ALL teams w/ correct answer get to shoot
You decide how many points to go for: 1, 2, or 3
What type of selection in shown in the graph
below?
White------------Grey--------------Black
Moth Coloration
PROKARYOTES•No membrane-bound nucleus
•Smaller in size
•Cell wall is present
•Unicellular
•Absence of internal membrane-bound organelles
If the half-life of a radioactive isotope is 2,500 years and you started out with a 40g sample, how much of the radioactive isotope would remain in 7,500 years?
3 half lives, so…
After 1(2,500yrs) 20g
After 2 (5,000yrs) 10g
After 3 (7,500yrs) 5g
Radioactive IsotopeStable Isotope
List 2 vocabulary words that you could use to describe an following organism with the
following alleles:Hh
Brown eyes are dominant to blue. What percentage of children from a blue-eyed male and a heterozygous brown-eyed female would
you expect to have blue eyes?
Incomplete dominance – Neither allele is dominant to the other, the heterozygote is a mix between the two alleles
RR R’R’R’R
What kind of mutation happened from the original strand of DNA
to the copied strand?
Original: ATC GCC TTA CGA
Copied: ATC CCC TTA CGA
What do the following things represent in a pedigree:
1. Square that is filled in
2. Circle that is left open
Which term best describes the genotype of individual II-4:
homozygous dominant
heterozygous
homozygous recessive
What is the enzyme that breaks the hydrogen bonds between nitrogenous bases in DNA before replication?
Helicase Remember: enzymes usually end
in “ase” “Helic” sounds like “helix” – it is
separating the double helix
Which term best describes the genotype of individual III-10:
homozygous dominant
heterozygous
homozygous recessive
Heterozygous: II-7 is homozygous recessive and HAS to pass on a
recessive allele to her offspring.
III-10 doesn’t express the trait, so she must have 1 copy of the dominant
trait.
Codominance: The alleles are like co captains - both are distinctly present in the
heterozygote
CWCW CRCR
RWRW
CWCR
Which DNA strand is constructed incorrectly?
Strand 1ATATGCCGTA
Strand 2TACGATGCTA
Strand 3TAGGATCGAT
DNA RNA Double stranded A pairs with T Sugar is
deoxyribose
Single stranded A pairs with U Sugar is ribose
HaploidThey no longer have copies from both mom and dad for each chromosome.
If they were diploid, they would have one copy from each parent.
What pairs up and then separates during:
A. Meiosis I
B. Meiosis II
(yes – you must get both correct)
The separation of genetic material is most similar to
Mitosis in which of the following?
A. Meiosis I
B. Meiosis II
What is 1 biological reason why an individual organism may be able to
outcompete others for resources?
Many answers possible:
•Beneficial genetic mutation
•Environmental change (climactic/geologic)
•Plague or other disease affects population
What is the mutation that is most detrimental (harmful) to the function of a protein if it appears early in the coding region for a gene? WHY?
Best answers will be one of the following: Nonesense mutation: type of point
mutation that creates a “STOP” codon early and protein synthesis stops.
Frameshift mutation not in a group of 3 bases: changes reading frames from that point onward and thus the order of amino acids in the proteincaused by deletions and insertions
A.) Mitosis: process by which the nucleus of a cell divides to create two
new nuclei, each containing an identical copy of DNA (make more
cells)
B.) Meiosis: process by which sex cells are created
The phenotypic ratio of a cross for a plant homozygous
for round and yellow seeds (RRYY) with a plant
homozygous for wrinkled and green seeds (rryy).
There were 2 adaptations of the primate eye that
were discussed in lecture.
What are they and why are they significant?
You are introducing Louis Pasteur and Gregor Mendel at a party. What would you say about each to highlight their
accomplishments?
