Question

whit did mendels cross pollination of pea plants prove

Answer 1

Pea plants have both male and female reproductive organs. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. In his experiments, Mendel was able to selectively cross-pollinate purebred plants with particular traits and observe the outcome over many generations.

Answer 2

Mendel is one the pioneers of the genetical science and phenomenons in the early biological studies.

He performed all of this experiments with the pea plants.

Because,pea plants can perform pollination in between themselves which is less time consuming and perfect scenario for any sort of accurate gentetical characteristics determining experiment.
