In the common daisy, genes A and B control flower color. Both genes have a dominant allele (A or B) and a recessive allele (a or b). At least one copy of each dominant allele is required for flowers to be colorful instead of white. -Predict the phenotypic ratio of the F2 progeny of a cross between two white-flowered plants, one homozygous for A and the other homozygous for B.
