Two true-breeding stocks of pea plants are crossed. one parent has red, axial flowers and the other has white, terminal flowers; all f1 individuals have red, axial flowers. the genes for flower color and location assort independently. if 1,000 f2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers?

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
