Population genetics describes the genetic composition of a population, including allele frequencies, and how allele frequencies are expected to change over time. The Hardy–Weinberg law describes the expected equilibrium genotype frequencies in a diploid population after random mating. Random mating alone does not change allele frequencies, and the Hardy–Weinberg equilibrium assumes an infinite population size and a selectively neutral locus. box cutter taped to wallWeb14 de ago. de 2012 · F ST is among the most widely used measures for genetic differentiation and plays a central role in ecological and evolutionary genetic studies.
