Population genetics relate to the behaviour of genes in populations and genetic structure of populations in terms of frequencies of alleles (genes), genotypes and phenotypes and the forces that affect them. Changes in the gene frequencies affect the genotypic frequencies which in turn influence phenotypic frequencies.

摘要

Population genetics relate to the behaviour of genes in populations and genetic structure of populations in terms of frequencies of alleles (genes), genotypes and phenotypes and the forces that affect them. Changes in the gene frequencies affect the genotypic frequencies which in turn influence phenotypic frequencies.
