Two organisms, AABB and aabb, are mated to produce an F1 that is self-fertilized. If the capital letters represent dominant, independently assorting alleles, how many different phenotypes will occur in the F2

16 phenotypes would would occur in f2.

Explanation:

it is 16 becuase this cross is a dihybrid cross. A dihybrid cross is a cross between two different lines/genes that differ in two observed traits. For genes on separate chromosomes, each allele pair showed independent segregation. If the first filial generation (F1 generation) produces four identical offspring, the second filial generation, which occurs by crossing the members of the first filial generation, shows a phenotypic (appearance) ratio of 9:3:3:1
