Gays and lesbians live in the society as epigenetic changes in one of the parents are passed to the embryo, American scientists claim, Vesti.ru informs.
Taking over from their parents the turn, a boy “failing to receive” testosterone, subsequently acquires the features of a girl, and a girl, on the contrary, becomes partly a boy.
As is known, an embryo becomes a boy, if a gene on the Y-chromosome triggers development of the testis, which approximately in 8 weeks of starting the development, produces male hormones, including testosterone. Thus, if there is a lack of Y-chromosomes, there will be no testosterone, hence, the embryo will turn into a girl. However, the experts claim that not everything depends on testosterone.
