  1. Rm, minimum number of recombination events; N, sample size of each species; s, polymorphic sites; nh, number of haplotypes; π, nucleotide diversity; h, haplotype diversity; p-distance, uncorrected p-distance between Aegithalos bonvaloti and A. fuliginosus; *, P< 0.05. CHDa, VLDLR9 and BRM15 are Z-linked loci, and TGFB2, RAG1 and MB are autosomal loci.
