Geneticist Konstantin Krutovsky stated that in the future the human “male” Y chromosome may disappear completely. In this case, using injections or genomic editing at stages of embryonic development, it is possible to completely reprogram the sex by affecting the primary sexual characteristics. This mechanism can be integrated into the genome, transmitted by inheritance and, ultimately, replace the Y chromosome if it is lost during the process of human evolution, the geneticist specified.

Genetic inheritance in humans, according to Krutovsky, has a rigid chromosomal type. If present XYthen is born manIf XX – woman. This ensures a stable one-to-one ratio in the form. However, as the scientist notes, in reality, slightly more boys may be born due to various factors.
In addition, there is another way to regulate sex – the dose method. By changing the expression of certain genes, it is possible to influence the development of both males and females. This method, for example, regulates sex in some species of turtles: in warm conditions, more females are born, in cold conditions, more males are born. According to the professor, such a dose effect can also be applied in the case of gender regulation in humans.
Krutovsky notes that artificial influence on a person’s sex using the dose method is also possible. This can be achieved by increasing the activity of certain genes, which will trigger male development. Such effects can be carried out through injections and maintained for a certain time, or fixed as permanent using genomic editing, Gazeta.Ru reports.
If this occurs in the early stages of development before puberty, then the formation of primary sexual characteristics will correspond to the chosen sex. This differs from the current idea of transition from one gender to another, Krutovsky emphasized.
