This is the diploid chromosome condition and the paired chromosomes are called homologous. Meiosis transforms a diploid cell into four haploid granddaughter cells, each having a single copy of each chromosome. The process helps increase the genetic diversity of a species.
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.ene 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. The more alleles available in a population, the more variation that can occur.
