Geometric Morphometrics to the Study of Skull Sexual Dimorphism in aLocal Domestic Goat Breed

The existence of sexual dimorphism in the White Rasquera goat breed has long been known, with males being larger than females. However, no study so far has explored this dimorphism separately in its size and shape components. Here we analysed twenty-three skeletonized skulls from adult animals (11 m...
