Chromosome 3 of corn carries three loci (b for plant color booster, v for virescent, and lg for liguleless). A test-cross of triple recessives with F1 plants heterozygous for the three genes yields progeny having the following genotypes:
+ v lg 325
b + + 275
b + lg 128
+ v + 112
+ + lg 74
b v + 66
+ + + 22
b v lg 18
Total 1010
What the distance between virescent and liguleless?

Three genes with recessive mutant phenotypes are located on the same chromosome in maize: waxy endosperm (wx), shrunken endosperm (sh), and virescent seedling (v). A plant with all three mutant phenotypes is crossed with a true-breeding, wild-type plant.

A purebred sweet corn plant that produces purple and smooth kernels pollinates a purebred plant that produces yellow and wrinkled kernels. When the F1 was testcrossed, four types of kernels on the cobs were observed in almost equal proportions: purple and smooth, purple and wrinkled, yellow and smooth, and yellow and wrinkled. Which of the following statement(s) are TRUE? I. The F1 plants can only produce purple and wrinkled kernels when selfcrossed. II. If the parent that produces yellow and...
