Genetic Control of Sexual Dimorphism
Institut National de La Recherche AgronomiqueStation de Recherches Avicoles, Domaine de l'Orfrasi&e, 37380 Nouzilly, France SUMMARY Selection could contribute to reduce sexual dimorphism of body weight and its negative consequences. Genetic differences between sexes at slaughter age were first studied. Heritabilities of male and female traits were different and genetic correlations between both...
متن کاملSexual Dimorphism in the Human Brain
In this paper I explpore what is currently known about sexual dimorphisms of the human brain and the developmental processes that produce them. Specifically, I focus on how genetic information brings about changes in the prenatal and neonatal hormonal environment, how that hormonal environment affects developing neural structures, and what the ultimate results of those changes are.
متن کاملGenetic variation in baboon craniofacial sexual dimorphism.
Sexual dimorphism is a widespread phenomenon and contributes greatly to intraspecies variation. Despite a long history of active research, the genetic basis of dimorphism for complex traits remains unknown. Understanding the sex-specific differences in genetic architecture for cranial traits in a highly dimorphic species could identify possible mechanisms through which selection acts to produce...
متن کاملSexual dimorphism and human enhancement.
Robert Sparrow argues that because of women's longer life expectancy philosophers who advocate the genetic modification of human beings to enhance welfare rather than merely supply therapy are committed to favouring the selection of only female embryos, an implication he deems sufficiently implausible to discredit their position. If Sparrow's argument succeeds, then philosophers who advocate bi...
متن کاملSexual dimorphism of the human cerebral pallium.
Sexual dimorphism was found regarding the cortico-medullary volume ratio in human brains throughout the age range, without the need for statistical analysis. After measurement of the areas of the whole pallium, cerebral cortex and cerebral medullary substance in 10 mm thick slices with the help of an image-analyzer, the total volume of the brain was calculated by integrating the volumes of each...
