  1. aMultiply values by 10−6.
  2. bMultiply values by 10−4.
  3. cGroup ratios that differ significantly (P <0.05) from the overall average ratio for the entire HGDP, based on random resampling of NRY and mtDNA sequences.
  4. H, number of different haplotypes (sequences); mpd ratio, ratio of the mpdNRY/mpdmtDNA; n, sample size; S, number of polymorphic sites; mpd ± SE, mean number of pairwise differences ± standard error; π ± SE, nucleotide diversity ± standard error.
