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 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 yiel...
متن کاملPolyploidy and gender dimorphism.
Miller and Venable (1) claimed that polyploidy is a “trigger of unrecognized importance” for the evolution of gender dimorphism, an idea originally proposed by Jennings (2) and Baker (3). In our opinion, their phylogenetic analysis of North American Lycium (Solanaceae) does not support the claimed associations between polyploidy, self-fertility, and gender dimorphism. There is no support (boots...
متن کاملReliability of sexual dimorphism in blood.
BACKGROUND Demonstration of sex chromatin forms an important aspect of human genetics. It also establishes the interrelationship between sex chromatin and an inactive X-chromosome. The term "sex chromatin" in blood refers to the "Drumsticks of polymorphonuclear leukocytes" or "Davidson's bodies". OBJECTIVE This correlative study evaluates the presence of these drumsticks quantitatively and al...
متن کاملThe Study of Sexual Dimorphism in The Morphometric Characteristics of the Skull of the Male and Female Zell Sheep
Introduction: The aim of the present study was to evaluate the morphometric differences of the skull in male and female Zell sheep. Methods: For this purpose, 30 heads (15 adult males and 15 adult female) of Zell sheep breed were collected from the local slaughter-house. The skulls were prepared using the boiling maceration according to the usual techniques, and the mandible was dissociated fr...
