BMI adults genetics twins international comparisons
2018/11/15
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.

Robustness Against Extinction by Stochastic Sex Determination in Small Populations
Robustness Against Extinction Stochastic Sex Determination Small Populations Populations and Evolution
2012/5/2
Sexually reproducing populations with small number of individuals may go extinct by stochastic fluctuations in sex determination, causing all their members to become male or female in a generation. In...
Involving men and boys in sexual and reproductive health (SRH) and HIV programmes is critical: for their own benefit, that of women and girls, and for enhancing gender equality. This publication combi...
