In a major scientific precedent, Japanese researchers said they have discovered the possibility of screening the chromosomes of masculinity and femininity in the semen, which may allow the control of the sex of the fetus in the future, but this will bring disastrous demographic consequences, if applied in humans.
According to the British newspaper Telegraph, the chromosome, which leads to pregnancy by a female, when he meets another chromosome of type (X) of the egg, carries an important molecule that can be controlled and turned into a critical element.The study, conducted at the University of Hiroshima in Japan, that this molecule, which is in the chromosome (x), can be slowed down, through a catalytic process.
On another level, a chemical can be added to some sensors in the semen, at which point, the male chromosome (Y), moves rapidly, completely separating itself from the slow chromosome of femininity.
When the experiment was conducted in mice, by artificial insemination, that is, by taking fast chromosomes, 90 percent of babies were male.
In the selection of slow chromosomes, 81 percent of newborns were born to females, which means that the technology allows for greater control over sex.
