WebA population gene pool refers to the total collection of genetic variation (alleles) within a population. It includes all the different versions of genes that exist in a population, and their frequencies. The gene pool is constantly changing through evolutionary processes such as natural selection, genetic drift, gene flow, and mutation. WebEach gene is a sequence of nucleotides at a specific place, or locus, along a particular chromosome. The DNA at that locus, however, can vary slightly in its nucleotide sequence and hence in its information content.
