Question

Difference between self pollination and cross pollination​

Answer 1

self pollination

1. Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms).

2. Firstly, if a given genotype is well-suited for an environment, self-pollination helps to keep this trait stable in the species.

cross pollination

1. Cross-pollination, also called allogamy, occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species. ... Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual.

2. Cross-pollination, also called heterogamy, type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.
