(a) Using the forked-line method, diagram the cross between a wheat variety with red kernels
(AABB) and a variety with white kernels (aabb) in which the two pairs of genes have a cumulative
effect. Classify the F2 progeny under the headings red, dark, medium, light, and white, and
summarize the expected results.
(b) From another cross between red and white kernel wheat varieties, 1/64 of the F2 plants had
kernels as deeply coloured as the red parent and 1/64 had white kernels. About 62/64 were
between the extremes.
