In the cases in which the X or the Y chromosomes were studied, the standardized π (nucleotide diversity) is shown (π values were multiplied by 4/3 or by 4, respectively, to make them comparable to autosomes). 

^aL, length per locus is indicated as number of kilobases sequenced. 

^bn, number of chromosomes. 

^cS, number of segregating sites. 

^dk, number of haplotypes observed. 

^echr, chromosome. 

^fNucleotide diversity for fourfold degenerate sites.
