n a certain plant, the dominant form of gene P codes for purple flowers while the recessive form results in pink flowers. The dominant form of another gene, A, activates the transcription of P, while the recessive form prevents the transcription of P and results in white flowers. A doubly-homozygous purple-flowered plant was crossed with a doubly-homozygous recessive white-flowered plant. The F1 progeny were then self-crossed to generate the F2 generation. Determine the ratios of genotypes and phenotypes for each generation.

Gregor Mendel discovered the fundamental doctrines of inheritance through his study of pea plants. He concluded that genes are inherited from each parent as separate, paired units.
Mendel observed how parental genes were segregated and if they showed up as dominant or recessive qualities in the offspring.
Mendel established three inheritance principles. The first is the law of segregation; the second is the law of independent assortment. The third is The Law of Dominance.
