Shannon’s Information Index, expected and observed heterozygosity, unbiased expected heterozygosity, and fixation index for the three populations.

Population	I	𝐻𝑜	𝐻𝑒	u𝐻𝑒	𝐹ST

I = Shannon’s Information Index = −1 * Sum (pi * Ln (pi)).
𝐻_𝑜 = observed heterozygosity = Number of Hets/N.
𝐻_𝑒 = expected heterozygosity = 1 − Sum pi^∧2.
u𝐻_𝑒 = unbiased expected heterozygosity = (2N/(2N − 1)) * 𝐻_𝑒.
F = fixation index = (𝐻_𝑒−𝐻_𝑜)/𝐻_𝑒=1−(𝐻_𝑜/𝐻_𝑒),
where pi is the frequency of the ith allele for the population and Sum pi^∧2 is the sum of the squared population allele frequencies.
