6. When a yellow female Labrador retriever was mated with a brown male, half of the puppies were brown and half
were yellow. The same female, when mated with a different brown male, produced only brown offspring. Explain these
results. What genetic principle is this an example of?
7. In some goats, the presence of horns is produced by an autosomal gene that is dominant in males and recessive in
females. A horned female is crossed with a hornless male. The F, offspring are intercrossed to produce the F2. What
