We have dealt mainly with only two genes, but the same principles hold for more than two genes. Consider the following cross:

Question

A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b; c/c ; D/d ; e/e
a. What proportion of progeny will phenotypically resemble (1) the first parent, (2) the second parent, (3) either parent, and (4) neither parent?
b. What proportion of progeny will be genotypically the same as (1) the first parent, (2) the second parent, (3) either parent, and (4) neither parent? Assume independent assortment.
