Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
The main source of genetic variation is a large population with a large gene pool.
genetic variation (from any of several sources) provides options to try.natural selection determines which of those options help the population most.
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
Genetic variation
Natural and Artificial Selection
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.

Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
