Reduced skull sexual dimorphism in a local sheep breed

Abstract

This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca, using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yield poor results.
