Show transcribed image text Two true-breeding pink-flowered plants are crossed to produce a pink F_1. The F_1 are interbred to produce an F_2 that consists of 317 pink plants and 73 red ones. Which of the following accounts best for this result? monohybrid cross with complete dominance monohyrid cross with incomplete dominance dihybrid cross with two complementary genes dihybrid cross with dominant suppression When two genes affect a trait so that both genes are necessary for expression of the trait, this gene interaction is called complementation epistasis penetrance suppression The phenotypic ratio of the F_2 in a cross involving genes that interact as described above would be 13:3 12:3:1 9:7 9:3:4 If members of one gene pair interact with another gene pair in such a way as to mask variation in the second pair, this type of interaction is called complementation epistasis penetrance suppression
