Bayesian inference (BI) trees and statistical parsimony networks based on sequences from each nuclear region. In trees, node support is indicated with Bayesian posterior probabilities and only posterior probabilities over 0.5 are shown. Shared haplotypes between pairs of subspecies are shown in black. In networks, each circle represents a single haplotype and the area of circle size is scaled by haplotype frequency. The filled black circles represent missing or unsampled haplotypes.
