In corn, the following allele pairs are on chromosome 9:
colored (C) vs. white (c)
aleurone color; starchy (Wx) vs. waxy
(wx) endosperm; and full (Sh) vs.
shrunken (sh) endosperm. F1 plants
heterozygous for all three alleles were test crossed; the resulting
progeny had the following phenotypic ratios:
colored, waxy, shrunken 116
colored, starchy, full 601
colored, starchy, shrunken 2538
white, starchy, shrunken 4
white, starchy, full 113
white, waxy, full 2708
white, waxy, shrunken 626
colored, waxy, full _____2...
