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.
