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.
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes.Gene flow is the movement of genetic information between different populations. This method increases genetic variation because introducing new alleles into a population increases the amount of diversity.ecause of this, mutations are usually selected against through evolutionary processes.
