Sexual Orientation, Prejudice and Segregation
Sexual Orientation, Prejudice and Segregation This paper examines whether gay and lesbian workers sort into tolerant occupations. With information on sexual orientation, prejudice and occupational choice taken from Australian Twin Registers, we find that gays and lesbians shy away from prejudiced occupations. We show that our segregation results are largely driven by those gay and lesbian worke...
متن کاملReduced 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 کاملSocial segregation is not a consequence of habitat segregation in red deer and feral soay sheep.
In many sexually dimorphic mammals, adults tend to form single-sex groups ('social segregation'). It has been assumed that social segregation is simply a by-product of sex differences in habitat use ('habitat segregation'). I tested this assumption on red deer, Cervus elaphus, and feral soay sheep, Ovis aries, using data on group composition, habitat use and space use collected on the Scottish ...
متن کاملNiche Segregation between Wild and Domestic Herbivores in Chilean Patagonia
Competition arises when two co-occuring species share a limiting resource. Potential for competition is higher when species have coexisted for a short time, as it is the case for herbivores and livestock introduced in natural systems. Sheep, introduced in the late 19(th) century in Patagonia, bear a great resemblance in size and diet to the guanaco, the main native herbivore in Patagonia. In su...
متن کاملSegregation distortion induced by wild-type RanGAP in Drosophila.
Segregation Distorter (SD) is a meiotic drive system in Drosophila that causes preferential transmission of the SD chromosome from SD/SD(+) males owing to the induced dysfunction of SD(+) spermatids. The key distorter locus, Sd, is a dominant neomorphic allele encoding a truncated, but enzymatically active, RanGAP (RanGTPase-activating protein) whose nuclear mislocalization underlies distortion...
