  • N, number of sequences used; π, average number of pairwise nucleotide differences per base pair Jukes–Cantor corrected (Nei 1987); Rm, minimum number of recombination events (Hudson and Kaplan 1985); 4GT, number of pairwise comparisons presenting the four gametic types over the total number of all pairwise comparisons; LD, pairs of sites showing significant linkage disequilibrium using Fisher's exact test (in parentheses after Bonferroni correction for multiple comparisons) over the total number of all pairwise comparisons ; ZnS, average of R2 values over all pairwise comparisons (Kelly 1997); ϕ-test, probability of observing the inferred nucleotide homoplasies under the assumption of no recombination, as implemented in SplitsTree4 (Huson and Bryant 2006).
