In corn, the alleles c and c result in colored versus colorless seeds, wx and wx in nonwaxy versus waxy endosperm, and sh and sh in plump versus shrunken endosperm. when plants grown from seeds heterozygous for each of these pairs of alleles were testcrossed with plants from colorless, waxy, shrunken seeds, the following phenotypes of progeny were observed. assume that interference in each interval is complete, so that the map distance in centimorgans (cm) corresponds to the percent recombination.
