FIGURE 4. Median-joining network (left) of the observed 36 haplotypes for RAG-1 nuclear DNA gene of 66 spottailed earless lizard individuals. Black circles indicate missing intermediates (unsampled). Cross-hatches represent mutational steps with all greater than four denoted by the number of steps. Bayesian analysis of the nuclear DNA RAG-1 gene (right). Numbers at the nodes are posterior probability values. Asterisks indicate values = 1.
