Statistical parsimony networks for four nuclear markers and species tree.

Networks for Chd1 (a), SWS1 (b), THY (c) and USP9x (d). Each circle in the network represents a single haplotype and the circle size is scaled by the haplotype frequency. Filled black circles represent missing or unsampled haplotypes. The numbers in the network represent mutational steps between haplotypes. (e) Species tree of R. sinicus lineages and outgroups estimated on the basis of four nuclear genes. Node support is indicated with posterior probabilities.
