Figure 3. Histogram of the observed distances (Kimura two parameters method) within Canary Islands and Iberian Peninsula groups (dark gray) and between them (light gray). Analysis of variance (ANOVA) (one-way) test results: F=5238 (p=0.000). Distances within homologous groups: Canary Islands (light gray): mean 0.008 (standard deviation [SD] 0.004; n=351); Iberian Peninsula (dark gray): mean 0.010 (SD0.006; n=666). Distances between heterologous groups (black): mean 0.033 (SD 0.005; n=999).
