Usually it is … Webf 2 is the expected squared difference of allele frequencies between two populations. Let’s assume we have M SNPs with allele frequency a j in population A and b j in population B. We can then estimate f 2 like this: f 2 ( A, B) = 1 M ∑ j = 1 M ( a j − b j) 2 = 1 M ∑ j = 1 M a j 2 − 2 a j b j + b j 2
