Morphometric variability in karyologically polymorphic populations of the wild Mus musculus domesticus in Greece

A number of geographically defined Robertsonian (Rb) populations of the wild house mouse Mus musculus domesticus Schwarz and Schwarz, 1943 occurs in several areas of Europe (including Greece) and northern Africa. A multivariate analysis of 26 morphometric characters studied in 6 populations from Greece was performed to detect possible morphological variability in populations having different chromosome number. A morphological polymorphism among all the studied populations was found but this is attributed rather to geographical than to karyotypic relations.
