More women than expected are genetically men (2016)
AF MORTEN BUSCH Kønskromosomerne giver normalt svaret på om du er kvinde eller mand. Kvinder har XX. Mænd XY. En lille gruppe af kvinder er dog rent genetisk mænd. De vokser op som kvinder med en kvindes krop, og de fleste opdager først langt inde i puberteten, at de er anderledes. Nu har danske forskere […]
