Not that kind of jeans!
A second pair of genes!
Oh meiosis! Dominant?
Or maybe not
What will they inherit?

A striped fruit fly is crossed with a non-striped fly. N = non-striped is dominant n = striped is recessiveWhat is the genotype of the striped parent?
A striped fruit fly is crossed with a non-striped fly. All 100 offspring are non-striped.
N = non-striped is dominant n = striped is recessive
What is the genotype of the non-striped parent?
The ‘B’ gene controls the color of a dog’s coat. The ‘R’ gene controls the texture.Which alleles, B, b, R, and/or r, would occur in all the offspring of the following parents?
BbRR x bbRr
The ‘B’ gene controls the color of a dog’s coat. The ‘R’ gene controls the texture.
Which trait would occur in all the offspring of the following parents?
bbRR x BbRr
Gene Dominant Recessive
Color B=Black b=White
Texture R=Rough r=Smooth
The law of independent assortment describes the inheritance of genes on different chromosomes and the behavior of chromosomes at the beginning ofa. meiosis 1b. meiosis 2c. mitosisd. all of the above.
If a heterozygous individual has a phenotype that is
intermediate between both types of homozygous
individual, the two alleles show _______ _______.
A child has a genetic disease caused by a single
gene. Neither parent has the disease. The allele that
causes the genetic disease is __________ .
An allele of a single gene causes a disease that affects many more males than females. This allele is
a. autosomal dominantb. autosomal recessivec. X-linked dominantd. X-linked recessive
A daughter inheritsa. more genes from her motherb. more genes from her fatherc. one copy of each gene from her mother and one copy from her father
A man who is heterozygous for the albino allele is married to a woman who is homozygous for normal skin color (Aa x AA). What fraction of their children would you expect to be albino?
If a son has an X-linked condition (e.g. color blindness or hemophilia), he must have inherited the gene for this condition from his ________.
A mother has type O blood and her husband has type AB blood. What blood types can their children have?
