Sex and the Single Splice
Drosophila male courtship offers a unique experimental system to uncover the molecular and neural basis of genetically preprogrammed behavior. In this issue of Cell, Demir and Dickson (2005) and Stockinger et al. (2005) demonstrate that this behavior relies on a single splicing of the fruitless transcript, and on a specific olfactory-based neuronal circuit.
متن کاملSex and the Single Chicken
This paper discusses results from some recent studies that point to the existence of fundamental differences between males and females in metabolism of energy. It is apparent that gender can influence the digestive capacity of chickens through endogenous energy losses, gut structure and function, and metabolic activity of gut microflora. This raises the question “Is there sexual dimorphism in o...
متن کاملGender Peer Effects: Evidence from the Transition from Single-sex to Coeducational High Schools (Boy Meets Girl)
Whether single-sex schooling can deliver better educational outcomes than coeducational schooling is a public concern. Parents are concerned about their children’s academic performance. Education policy makers are keen to find ways to improve student outcomes, and changing the gender composition of schools might be a cost-effective option. To understand students’ academic performance in coeduca...
متن کاملSex and the single neuron: pheromones excite.
Pheromones are potent chemical signals used by animals across all phyla to control reproductive function and social behavior. Whereas there are few examples of the effects of pheromones on human behavior (fortunately?), in other species, such as laboratory mice, the effects of pheromones have been shown to be dramatic: a female mouse might abort a pregnancy if exposed to pheromones from a male ...
متن کاملSex Determination: One for a boy, two for a girl?
Sex determination in flies relies on the different ratio of X chromosomes to autosomes in XX females and XY males. Mammals have a male-determining Y-linked gene, but may retain dosage-related elements.
