Figure 5From: Asymmetric reproductive isolation between terminal forms of the salamander ring species Ensatina eschscholtzii revealed by fine-scale genetic analysis of a hybrid zoneMaximum likelihood profiles for the centers (A) and widths (B) of clines. Cline centers for the nuclear loci are concordant with each other, while the mitochondrial cline is shifted significantly to the west (A). There is no significant difference in cline widths (B).Back to article page
