Ralph's wants to breed two of his prize bulldogs. For the dominant alleles, he has selected small ears (E) and a curly tail (T). Linus, the male bullbog, is homozygous dominant for both traits. Lucy, the female, is heterozygous dominant for both traits.
A. What are Linus's and Lucy's genotypes?
B. What percent of their pups will have small ears and curly tails?
C. What percent will have large ears (e) and straight tails (t)?

Okay, so we have one homozygous, the prefix "homo" means "same" and we know that the male's genotype is dominate, so with the prefix "same" or "homo" we know the male's genotype must be EE, and TT. We also know that the female's genotype is heterozygous, and knowing that "hetero" means opposite, we know that she has the two opposite types of genes Ee and Tt

i hope this helps
