Detailed explanation-1: -The P generation, or parental generation, is the first generation of plants in a cross-pollination experiment. The offspring or generation that a P generation produces is called the F1 generation, and the F2 generation is reproduced from the F1.

Detailed explanation-2: -Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
