In population genetics, F-statistics (also known as fixation indices) describe the level of heterozygosity in a population; more specifically the degree of (usually) a reduction in heterozygosity when compared to Hardy–Weinberg expectation. F-statistics can also be thought of as a measure of the correlation between genes drawn at different levels of a (hierarchically) subdivided population. This correlation is influenced by several evolutionary processes, such as mutation, migration, inbreeding, natural selection, or the Wahlund effect, but it was originally designed to measure the amount of allelic fixation owing to genetic drift.The concept of F-statistics was developed during the 1920s by the American geneticist Sewall Wright, who...
