  1. N = sample size
  2. Na = No. of Different Alleles
  3. Ne = No. of Effective Alleles = 1/(Sum pi2)
  4. Ho = Observed Heterozygosity = No. of Heterozygotes/N
  5. He = Expected Heterozygosity = 1 - Sum pi2
  6. He = Unbiased Expected Heterozygosity = (2 N / (2 N-1)) * He
  7. Fis = Fixation Index = (He - Ho) / He = 1 - (Ho / He)
  8. Where pi is the frequency of the ith allele for the population & Sum pi2 is the sum of the squared population allele frequencies
