  1. r2 = ZnS (Kelly 1997), average of r2 over all pairwise comparisons; D' (Lewontin 1964)
  2. a Distance in bp, but the numbers in bracket were calculated based on the function between distance and r2 in kb.
  3. b The significant association between polymorphic pairs determined by the two-tailed Fisher's exact test. Number in bracket means the percentage, which significant pairs accounted of total pairwise comparisons.
