Question

1. In the dark, most dogs' eyes reflect a yellowish-green light. However, when homozygous for a
recessive allele called ruby eye (e), the light reflected is red. A dominant allele (A) results in
black hair, while the recessive allele (a) produces a black and tan pattern when homozygous.
A black and tan female crossed to a black male produced nine pups, all black. In the light of a
flashlight the eyes of the mother and four of her puppies shone red. (Show your work)


a. What is the genotype of the father with respect to reflectance of light?







b. What is his genotype with respect to coat color?

Answer 1

The genotype of father with respect to reflectance of light will be Ee (Yellowish-green). Explanation: As homozygous ruby eye (e) shown red, so genotype of eye which reflected red light will be ee. Whereas genotype of eye which reflected yellow…
