Question

Mention two strategies to prevent self pollination

Answer 1

Heyyy!!!

The strategies evolved to prevent self-pollination in flowers are: 1) Dichogamy- The maturation of anthers and stigma at different time in a bi-sexual flower which prevents self-pollination. 2) Self-incompatibility: The pollen grains of a flower are not capable of completing growth on the stigma of the same flower.

Answer 2

Answer:

There are two strategies involved in preventing self-pollination in flowers:

Dichogamy – It refers to the production of male and female reproductive organs at different times in order to prevent self-fertilization.

Self-incompatibility – It is a genetically controlled mechanism in which pollen grains of a flower are unable to completely grow on the stigma of the same flower.
