On chromosome 3 of corn there is a dominant gene (A1), which together with the dominant gene (A2) on chromosome 9, produces colored aleurone. All other genetic combinations produce colorless aleurone. Two pure colorless strains are crossed to produce an all colored F1. a) what were the genotypes of the parental strains and the F1?

b) what phenotypic proportions are expected among F2?

c) what genotypic ratio exists among the white F2?
