Answer :
i think it is B. It takes four generations of offspring to identify the parents' factors
Mendel's cross-pollination of pea plants proved that each parent only passes on one/half of its hereditary factors to each offspring.
What is cross pollination?
Cross pollination involves the process whereby pollen from another plant is used to fertilize the stigma of another plant of the same species.
Mendel cross pollinated pea plants in his experiment.
During his experiments, he was able to identify recessive and dominant traits or hereditary factors.
He also proved that each parent only passes on one/half of its hereditary factors to each offspring.
Therefore, Mendel's cross-pollination of pea plants proved that each parent only passes on one/half of its hereditary factors to each offspring.
