WebJun 7, 2024 · What does FST stand for in population genetics? F-statistics: a measure of genetic structure developed by Sewall Wright (1969, 1978). FST is the proportion of the total genetic variance contained in a subpopulation (the S subscript) relative to the total genetic variance (the T subscript).
