In dogs spotted fur (S) is a dominant trait. The recessive allele (s) results in brown fur. One dog is heterozygous for spotted fur and mates with a dog homozygous recessive, and they have puppies. Which best describes the puppies?



Answer :

Dog One - Ss Dog two - ss

The puppies will have a 1/2 chance of having either spotted or brown fur, however, fertilization is random and so this may be different. Here's my table of working (rubbish computer-mouse drawn too) in case you need it!
