Question

List threestrategies that a bisexual flower can evolve to prevent self pollination

Answer 1

self incompatibility, herkogamy, heteromorphism

Answer 2

The three strategies that a bisexual flower can evolve in order to prevent self pollination are as follows :-

• The release of pollen grains and the receptivity of the stigma are not synchronised.

• The anther and stigma are positioned in such a way that the pollen grain can not come in contact with the stigma of the same flower to which it belongs.

• The flower can evolve to have self-incompatibilty.
