Question

Imagine that we mate two black labrador dogs with normal vision and find that three of the puppies are like the parents, but one puppy is chocolate with normal vision and another is black with pra (progressive retinal atrophy, a serious disease of vision). we can conclude that the same alleles that control coat color can also cause pra. both of the parents are homozygous for both traits. the alleles for color and vision segregate independently during gamete formation. the alleles for color and vision segregate dependently during gamete formation. previous next

Answer 1

For the answer to the question above, I believe the answer based on the given information above, the alleles for color and vision segregate independently during gamete formation. That's why the two Labradors are different. The other one is healthy and the other one is not.
