Give scientific reasons for the following statements:
Extinction of species can be prevented in sexually reproducting organisms.

Explanation

In sexual reproduction, a zygote is formed by the union of sexual reproductive cells through fertilisation.
`rarr` The male reproductive cell is formed in father.s body and female reproductive cell is formed in mother.s body.
`rarr` Thus, offspring gets genetic material (DNA) of two different parents. So, there is variation in offspring.
`rarr` This variation helps the individual to get adapted to the changing environment. So, organism can live better.
`rarr` Through variation and adaptation, species extinction can be prevented and continuity of life is maintained. So, extinction of species can be prevented in sexually reproducting organisms.
