Genetic variation is stored in a population's gene poolâthe combined alleles of all of the individuals in a population. allele frequency An allele frequency is a measure of how common a certain allele is in the population.
Your genes have alleles, which are different forms of the same gene. Alleles are like a code for your body that determine hair color and eye color, height, and other genetic features. Genetic variation is the variation in alleles and genes, both within and among populations. Think of a population as a family unit.Within your family of closely-related individuals there is genetic variation. Within a neighborhood, there are many families, and so there is also genetic variation among that larger group.here 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.
