Are pollination and fertilisation necessary in apomixis? Give reasons.
In apomixis pollination and fertilisation are not necessary. The reasons for its support are as follows: $(i)$ Embryo is formed without meiosis from megaspore. Ovules are diploid and converted into embryo. $(ii)$ Embryo is formed from the cells of diploid nucellus in which egg cell is diploid. It gets converted into embryo by non fertilised genetic way.
