Guess the lover through the gene

Emotional tests may be interesting, but genetic testing of adequate levels can be a better way to know if your other half is able to betray.

A new study found a group of genes, related to immune function, can judge how much a woman is attracted to her partner and how loyal she is to her partner. Couples with a major histocompatibility complex (MHC) are not the same, having the greatest sexual harmony.

The MHC genome controls the production of some protein receptors that cover the cell surface. These receptors send signals to the body's immune system to tell if a cell is a legal or intruder. With many versions of MHC, the immune system will be able to identify more foreign cells. Therefore, the combination of different MHC sets will help create healthier common children.

Psychologist Christine Garver-Apgar at the University of New Mexico, USA, and colleagues studied 48 couples from 18 to 35 years old. They took the gene from the cells on the cheeks of the participants.

These couples also completed the questionnaire in two stages, when the woman is most likely to get pregnant during her period and when they are safe. Questions to assess the satisfaction of relationships, the satisfaction of sex life, the number of partners and attitudes about sex in general.

The results show that the exact opposite is attractive to each other, especially when women are in the most sensitive phase of the menstrual cycle."When the MHC resemblance increases, women are more likely to be distracted by their partners and more vulnerable to other guys, especially when she is at the fullest," says biologist Randy. Thornhill at the University of New Mexico said.

Not only are they directed towards others, but women with high levels of similar MHC with their partners also have more sex with other men.

"This shows that women looking for out-of-stream relationships are a reason for it, perhaps to search for better genes and match themselves," Garver-Apgar said.

Men have no discrimination about such sexual inspiration with their partners. This also supports the theory that men do not spend a lot of energy on reproduction. They simply went to bed when there was a chance.
