Explanation:
Detailed explanation-1: -Gregor Mendel’s “P” generation consisted of homozygous purple flower plants crossed with homozygous white flower plants. What were the results of this cross? 100% heterozygous purple flower offspring since purple is dominant.
Detailed explanation-2: -In the given cross, the allele for purple flower “P” is dominant over the allele for while flower “p". So, the cross between PP (purple flowers) and pp (white flowers) plants will obtain all plants with purple progeny (Pp).
Detailed explanation-3: -The offspring of the P parent generation are called the F1 (for filial, or “offspring”) generation.
