Question

which of mendels generations was allowed to self - pollinate?
f₁ generation
p generation
f₁ generation and f₂ generation
p generation and f₂ generation

Explanation:

Mendel started with the P (parental) generation, which were pure - breeding plants. He then cross - pollinated the P generation to get the F₁ generation. After obtaining the F₁ generation, he allowed the F₁ generation to self - pollinate to produce the F₂ generation. The P generation was used in cross - pollination experiments (e.g., cross - pollinating different pure - bred pea plants for traits like tall and short).

Answer:

A. F₁ generation
