Women are not sexually interested in men who have a genetic background similar to theirs

A study by researchers at the University of Mexico City indicates that when a man's genetic background is similar to that of a woman, his sexual attraction may diminish. This is because very small genetic differences give the safety of women who are ready at any time to reject the advances made to them. On the other hand, men are not interested in the similarity of the genetic background, the study mentioning that this is the reason why men are not very pretentious when it comes to a sexual partner.

The researchers pointed out that so far this reaction has only been discovered in animals.

But, like these, humans possess a genetic background that determines cell surface encoding, a coding used to identify the body's own cells and to attack foreign cells.
