Table 2 Results of the analysis of molecular variance (AMOVA). For each marker groups were defined according to biogeographic areas (A) within the “Slender” morphotype; (B) within the “Stocky” morphotype and (C) between morphotypes (d.f.: degrees of freedom; % var: percentage of variation)

From: Evidence of genetic isolation between two Mediterranean morphotypes of Parazoanthus axinellae
