The main source of genetic variation is a large population with a large gene pool.
Crossing over is the major source of genetic variation during meiosis.
adaptation or natural selection
Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
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 is a direct results of many sources of genetic material and their unconstrained interaction. The larger the population and the fewer restrictions on how they can be integrated the more diverse the genetic variation. This allows for better natural selection and also reduced the ability of disease from affecting the entire population. The founder effect describes genetic variation in communities established by few people. Inbreeding in small closed communities leads to abundances of recessive ailments. This can be seen in hereditary royal families and closed remote communities.
The two sources of genetic variation in a cell during Meiosis are crossing-over during synapse and independent assortment.
Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
Mutation and the genetic recombination in sexually reproducing organisms.

Natural and Artificial Selection
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.

Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.

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