چکیده مقاله :
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.
در این مطالعه با استفاده از روشهای اندازهگیری ابعاد هندسی ظاهری، میزان دو شکلی جنسی در نژاد گوسفند فارداسکا بومی کاتالانیا (واقع در شمال شرق اسپانیا) برآورد شده است. برای این آنالیز، مجموعاً 18 نمونه جمجمه (2 نر بالغ و 16 ماده بالغ) مورد مطالعه قرار گرفت. نتایج نشان داد که این نژاد از نظر جمجمه دو شکلی نداشته و بنابراین تعیین جنسیت آن با استفاده از علایم و نشانههای اشاره شده در این مقاله، نتایج ضعیفی را در برخواهد داشت.
