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's experiments involved crossing pure - breeding (P generation) plants. The offspring of the P generation is the F₁ generation. After obtaining the F₁ generation, Mendel allowed the F₁ generation to self - pollinate to produce the F₂ generation. The P generation was not self - pollinated in the context of generating the F₂ generation (the P generation was cross - pollinated to get F₁).

Answer:

F₁ generation
