Question

prepoteny and dichogamy​

Answer 1

Answer:

Prepotency:-

Pollen prepotency: In this mechanism, the pollen of a different flower germinates faster than of the same flower thus preventing autogamy.

Dichogamy:-

In pollination: Structural …receptive, a situation known as dichogamy. The more usual form of dichogamy, which is found especially in such insect-pollinated flowers as fireweed (Epilobium angustifolium) and salvias (Salvia species), is protandry, in which the stamens ripen before the pistils.
