Sample Question
Some dogs have erect ears; others have drooping ears. Some dogs bark when following a scent; others are silent. Erect ears and barking are due to dominant alleles located on different chromosomes. A dog homozygous for both dominant traits is mated to a droopy-eared, silent follower. The expected phenotypic ration in the F1 generation is

9:3:3:1

100 percent of one phenotype

1:1

1:2:1

None of these
