a. In mice, dark coat color is dominant over albino and short hair is dominant over long hair. Assume that these two traits are caused by two independently assorting genes. Hair color is determined by the (D/d) alleles. Hair length is caused by the (S/s) alleles. Two mice are crossed and result in the following progeny: 20 short-haired, dark mice and 21 short-haired, albino mice. What is the most likely genotype for the parents? b. The researcher who is counting the mice suddenly realizes that the trait is probably X-linked as all the albino mice are one sex and all the dark mice are theoppositesex. What can you conclude about the 2 parental mice with regard to the hair color trait?

Question
a. In mice, dark coat color is dominant over albino and short hair is dominant over long hair. Assume
that these two traits are caused by two independently assorting genes. Hair color is determined by the
(D/d) alleles. Hair length is caused by the (S/s) alleles. Two mice are crossed and result in the following
progeny: 20 short-haired, dark mice and 21 short-haired, albino mice. What is the most likely genotype
for the parents?
b. The researcher who is counting the mice suddenly realizes that the trait is probably X-linked as all
the albino mice are one sex and all the dark mice are theoppositesex. What can you conclude
about the 2 parental mice with regard to the hair color trait?
