When a wheat variety with red kernels (homozygous for two non allelic and independent dominant genes) is crossed with white kenneled wheat (homozygous for two recessive non allelic independent genes), the phenotypic ratio in the F2 generation would be________________?

Question

Accepted Answer

1:4:6:4:1. The question describes a quantitative trait controlled by two independent dominant genes (polygenic inheritance). The phenotypic ratio for the F2 generation in such cases follows a binomial expansion pattern of (3:1)^n. For n=2, the ratio is 1:4:6:4:1.
