Flower color in a certain plant is controlled by a gene with two alleles, or variants, called A and a. Every plant has two alleles that make up the genotype, or genetic composition. In turn, the plant's genotype determines the plant's phenotype, or outward appearance.

In a certain garden, the genotype and phenotype frequencies of this plant are as follows.
