If a wheat plant with red kernels, homozygous for two independent dominant genes (non-allelic), is crossed with a white-kernelled wheat plant homozygous for the corresponding recessive alleles, what phenotypic ratio is expected in the F2 generation?

Explanation

When two genes independently and dominantly control a trait, crossing homozygous dominant with homozygous recessive results in F1 heterozygotes. The F2 generation follows a binomial expansion for two genes, producing a phenotypic ratio of 1:4:6:4:1, reflecting the distribution of genotypes and resulting kernel colors.
