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 genotypes and phenotypes of the F₁ progeny of a cross between two white-flowered plants, one homozygous for A and the other homozygous for B.

The cross between two white-flowered plants, one homozygous for A and the other homozygous for B, can be represented as aaBB x AAbb. The F₁ progeny will all be heterozygous for both genes (AaBb) and will have colorful flowers because they have at least one copy of each dominant allele.
