How does genetic variation increase an entire species chance of survival

Genetic variation refers to the difference in the genetic material of the offspring compared to their parent. The changes in gene occur as a result of the natural selection pressure and the new combination of sequences is formed in the gene in individuals.

The individuals with variation are then selected by nature based on the basis of how much these genetic variations prove beneficial:

1. The new combination of sequence could allow the population to adapt to the new environment

2. The new combination can allow the population to survive and when the population survives then the reproduction rate of population increases.
