The red kernel color in wheat is caused by the presence of, Ask an Expert

Academics

The red kernel color in wheat is caused by the presence of at least one dominant allele from each of the two idependently segregating gene pairs. Wheat plants with rrbb genotypes have white kernels, and plants with genotypes R-bb and rrB- have yellow kernels. If you cross a plant true breeding for red kernels (RRBB) with a plant true breeding for white kernels (rrbb) you get an all red F1 with the genotype RrBb.

a) If two F1 red plants are crossed, what are the expected phenotypes and ratios for the F2?

b) You cross two plants true breeding for yellow kernels and get 100% of the offspring are red kernel plants. What are the genotypes of the two yellow plants?
