Question

When does self-pollination occur?​

Answer 1

Self pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

Answer 2

Answer:

A flower is self-pollinated (a “selfer”) if pollen is transferred to it from any flower of the same plant and cross-pollinated (an “outcrosser” or “outbreeder”) if the pollen comes from a flower on a different plant
