Which of Mendel's generations was allowed to self-pollinate? F1 generation P generation F1 generation and F2 generation P generation and F2 generation

f1 gen

The correct answer is an F1 generation.

The parent plants in the experiments conducted by Mendel are considered as the P (for parent) generation. The F1 stands for the first filial generation, which was obtained on cross-pollinating the parent plants. The F2 stands for the second generation, which is attained after self-pollinating the F1 generation plants.
