Web5.2 Understanding F ST - the fixation index. F ST, also known as the fixation index, is an extremely important statistic in population genetics, molecular ecology and evolutionary biology.It is also arguably one of the most famous population genetic statistics you will encounter. F ST essentially measures the level of genetic differentiation between two or … WebPopulation 1: 500 Population 2: 100 Population 3: 1,000 Remember that the number of alleles is TWICEthe number of genotypes. Step 1. frequencies: Each homozygote will have two alleles, each heterozygote will have one allele. Note that the denominator will be twice Ni(twice as many alleles as individuals). Eqns FST.1 Step 2.
