Asexually reproducing organisms can make exact copies of themselves. But it is impossible that all organisms produce similar organisms. In sexually reproducing organisms there is variation due to the combination of genes. The variation may be in their structural and physical appearance.

*Importance of variation*

In nature, variations occur during sexual reproduction. If this variation is beneficial to the species, it is selected and remains in the population. This is because the variant species are more adapted. Therefore, they can survive better and reproduce to pass the genes to the offsprings.
Variations are very important for organisms to survive because if there were no variations among living organisms there would have been no evolution or change and natural conditions do not remain constant they keep on changing. If variations stop then we would not be able to adapt to the changing conditions and can prove it

Variation is important for the survival of particular organism in the altered environment that is it helps in the better survival of an organism in the changing the world.
