Question

it is said that if gamete is present the variation will be there . The why it is not happening in case of self pollination in plants​

Answer 1

Answer:

Explanation:

In self- pollination, since both the male and female gametes share the same genes, there is no genetic variation seen which is necessary for a better, more productive offspring. So, most plants have many mechanisms that they employ to avoid self -pollination and promote cross-pollination.
