Define self-pollination ?

Assertion : Self-incompatibility is a genetic mechanism which prevents self-pollination and thereby fertilisation by inhibiting either pollen germination or pollen tube growth in the pistil. Reason : In gametophytic self-incompatibility, the incompatibility reaction is determined by the genotype of the sporophytic tissue of the plant from which the pollen is derived.

A mechanism to prevent cross pollination is

The genetic mechanism which prevents selfpollen from fertilising the ovules by inhibiting pollen germination on the pistil of same flower is called

Device for self - pollination is :

Flowers preventing self pollination is called

Assertion :- Non synchronised pollen release and stigma receptivity is of evolutionary significance. Reason :- It prevent self pollination and promote more genetic variability
