In sweet pea, red flower color is controlled by two genes involved in the anthocyanin pathway, A and B. Both genes are required for expression, so that a recessive pair of alleles at either locus would result in a pink phenotype. If anAaBb plant were allowed to self-cross and you got only red and pink flowers, what dihybrid ratio would you expect in the offspring?
