Haplotype network for Hypogeophis rostratus inferred from nuclear DNA: a) bdnf, b) rost5, c) brev5, d) pomc. Size of the haplotypes are indicative of number of individuals in the haplotype and colors indicate island population as referred to in the key. Small black circles refer to mutational steps between haplotypes and open circles represent extinct or unsampled haplotypes
