The gene for round peas (R) in a pea plant is dominant over the gene for wrinkled peas (r). In a cross between one heterozygous parent and one homozygous wrinkled pea parent, we can predict that what percentage of the offspring will have round peas?
100%
50%
75%
25%

In a certain breed of dogs, brown fur (B) is a dominant trait over yellow fur (b). Gregory owns a brown female. She produced a litter of offspring that includes two brown and two yellow puppies. The only thing Gregory knows about the male is that he was of the same breed. Which of the following represents the genotype combinations that are possible for Gregory’s dog and the father of this litter of puppies?
Mother = BB x Father = bb
Mother = BB x Father = Bb
Mother = Bb x Father = Bb
Mother = Bb x Father = bb
