Na = no. of different alleles, Ne = no. of effective alleles = 1/(p^2 + q^2), I = Shannon’s Information Index = −1* (p * Ln (p) + q * Ln(q)), H = diversity = 1 − (p^2 + q^2), uh = unbiased diversity = (N/(N−1)) * h (where for haploid binary data, p = Band Freq. and q = 1 − p), and %P = percent polymorphic loci
