Reduced Skull Sexual Dimorphism in a Local Sheep Breed

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 speci-mens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimor-phic, so sex determination using landmarks described here as criteria is likely to yield poor results.
