The two main sources of genetic variation are mutations and recombinations of genes as a result of sexual reproduction. A mutation is a permanent change in the DNA within a gene. Continue Reading. Some mutations, which affect all cells in an organism, are inherited from a parent.
But then there is no longer any variation for further evolution. The possibility of continued evolution therefore is critically dependent on renewed variation. For a given population, there are three sources of variation: mutation, recombination, and immigration of genes.utations are the source of variation, but the process of mutation does not itself drive evolution. The rate of change in gene frequency from the mutation process is very low because spontaneous mutation rates are low (Table 24-9).
