El índice de fijación (FST) es una medida de la diferenciación de la población debido a la estructura genética. Con frecuencia se estima a partir de datos de polimorfismo genético, como polimorfismos de un solo nucleótido (SNP) o microsatélites. Desarrollado como un caso especial de las estadísticas F de Wright, es una de las estadísticas más utilizadas en genética de poblaciones. WebFeb 20, 2024 · Fst measures the amount of genetic variance that can be explained by population structure based on Wright’s F-statistics ( Wright, 1965 ), while Nm = [ (1/Fst) − 1]/4. An Fst value of 0 indicates no differentiation between the subpopulations while a value of 1 indicates complete differentiation ( Bird et al., 2024 ).
