Özet:

 The purpose of this study was to use a geometric morphometric approach to ascertain the gender-related differences in the morphology of the domestic buffalos skull and mandible. The skulls yielded a total of 20 main components. The first principal component PC1 alone was responsible for 37.066 of the variation among these principal components. The first principal component PC1 alone was responsible for 26.242 of the total variation among the lateral principal components. PC1 showed a medial extension of the posterior portion of the ectorbital, while PC2 showed a lateral extension. In PC2 and PC3, the right facial tuber displayed a cranial and linear expansion, respectively. In PC1, the left facial tuber was directed caudally, and in PC2, it was directed cranially. The anterior border of the first premolar had a caudo-ventral extension in PC1 and a cranio-dorsal extension in PC2 and PC3, according to lateral studies. In PC1 and PC2, the anterior side of the ectorbital displayed a caudo-dorsal extension, but in PC3, it displayed a dorsal extension. The anterior margin of the first premolar displayed a caudal extension in the extension evaluation of the three principal component analyses with the highest values in the mandibles, where the data are completely integrated with one another. PC1 showed a caudo-dorsal extension, PC2 showed a cranio-dorsal extension, and PC3 showed a dorsal extension of the landmark at the level of the incisura vasorum facialum. It is anticipated that this research will add to the body of knowledge about a particular breed, zoo archaeology, or be used as an animal model in relevant health professions.
