Figure 6From: Island biology and morphological divergence of the Skyros wall lizard Podarcis gaigeae: a combined role for local selection and genetic drift on color morph frequency divergence?Relationship between neutral divergence and morph divergence. (A) Relationship between the pair wise population comparisons (FST) calculated from color morph frequencies (assuming a single locus character) and neutral genetic divergence (FST obtained from 18 microsatellite loci). The relationship is positive and statistically significant when data from all categories are included: y = 0.09 + 0.44*x; r2 = 0.20; F = 6.37; df = 1, 26; P = 0.02. There is also a significant relationship when only the mainland populations are included (squares; full line; y = -0.07 + 5.59*x; r2 = 0.83; F = 19.41; df = 1, 4; P = 0.01) and when only mainland-island comparisons are included (triangles; dashed line; y = -0.04 + 1.19*x; r2 = 0.60; F = 21.01; df = 1, 14; P = 0.0004). There is no significant relationship between color morph divergence and neutral divergence when only island populations are compared (dots). (B) Distribution of mean pair wise FST-values for the 18 microsatellite loci (black) and the mean pair wise FST-values that were calculated from the throat color morph frequencies (assuming a single locus character; (in white)).Back to article page
