^aNumber of chromosomes sampled after predicted recombinants were omitted (see the “Subjects and Methods” section).

^bML estimate of nucleotide variability per locus from the GENETREE analysis.

^cEffective population size derived from θ_ML and μ=9×10^-5/locus/generation (see the “Results” section).

^dMean age estimate (in kyr) derived from N_e, with a generation time of 20 years (see the “Results” section).

^eThe single A− allele is omitted (see the “Results” section).
