From: Genetic variation and relationships in the mitochondrial DNA D-loop region of Qinghai indigenous and commercial pig breeds

Code Breed/Population Size S H Hd ± SD Pi K
CHN-QH Bamei 115 10 10 0.491 ± 0.055 0.00264 1.15
DUR Duroc 101 18 11 0.732 ± 0.033 0.00947 4.12
LAN Landrace 108 18 18 0.853 ± 0.02 0.01567 6.815
YOR Yorkshire 165 27 24 0.856 ± 0.018 0.01559 6.768
  1. S: Number of polymorphic (segregating) sites
  2. H: Number of haplotype
  3. Pi: Nucleotide diversity, Nei 1987, eqs. 10.5 or 10.6 (Masatoshi Nei)
  4. K: Average number of nucleotide differences; Tajima 1983, eq. A3 (Tajima)
  5. Hd ± SD: Haplotype (gene) diversity and sampling variance, Nei 1987, eqs. 8.4 and 8.12 but replacing 2n with n. The standard deviation (or standard error) is the square root of the variance (Masatoshi Nei) [13]
