You are doing a genetics experiment with Drosophlia melanogaster, the fruit fly. In the "P" generation, you cross 2 true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All the flies in the F1 generation are brown and have normal wings. Assume that the genes are not found on sex chromosomes. Indicate color alleles as "B" for brown, "b" for black, "W" for normal wings, "w" for wingless. (A) What are the genotypes in the P generation? (B) What are the genotypes of the flies in the F1 generation?

Question
You are doing a genetics experiment with Drosophlia melanogaster, the fruit
fly. In the "P" generation, you cross 2 true-breeding flies. The female parent
is brown and wingless and the male parent is black with normal wings. All
the flies in the F1 generation are brown and have normal wings. Assume
that the genes are not found on sex chromosomes. Indicate color alleles as
"B" for brown, "b" for black, "W" for normal wings, "w" for wingless.
(A) What are the genotypes in the P generation?
(B) What are the genotypes of the flies in the F1 generation?
