  • a The average pairwise FST, θπ; θW, and D values were based on 2,599 biallelic, nonrecombinant SNPs.

  • b The average tip-to-tip distance reflects branch lengths on an ML tree corrected for recombinant sites.

  • c The sum of pairwise Ψ values was based on 2,595 biallelic, nonrecombinant SNPs where ancestral and derived alleles were assigned.
