The genetic variation enable a particular species to withstand the adversities of Nature by way of selection on the basis of the principle of survival of the fittest.
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
It promotes genetic variation.
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Sexual Reproduction Genetic mutation
If a population dwindles, there is low genetic variation and a species may risk extinction.
Genetic bottleneck causes very little genetic variation and can cause genetic drift.
Genetic variation, which can lead to evoloution, and then potentially a new species.

Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.

Gentic variation is mearsured by the number of species in the given area not.
