Partner's jealousy, considered from the perspective psicosociobiológica, constitute a response that has been maintained consistently comply, the advantages for genetic survival of individuals. In both sexes, jealousy, protect and guarantee the perpetuation of one's genes against those of others.

For males with a clear difficulty to ensure that the offspring of a female is itself determined, jealousy protect against genetic heritage of potential rivals. For females, the difficulty of establishing gene that guarantee no offspring, but is presented with the need to ensure the protection of the same. In this case the jealousy protect her and her offspring of the possible abandonment and care granti by the male.

This different between males and females need the face of genetic survival, explain why to the different evolutionary risks, males will primarily focus on protection from sexual threat from other males and females against the threat regarding the fidelity and pareja.Para emotional stability of both jealousy is a response to the danger that their genes eventually reach not transmitted to future generations.

The different impact in terms of genetic survival, which for both sexes would have the aprición of a third individual, also explain the different types of response observed jealous men and women. In fact, men are more precupados by sexual fidelity of their partners, while women are more for the emotional fidelity.

His works reveal that 60 percent of men over sientirían disgruntled at the fact of sexual intercourse, while 84 percent of the women demonstrated more opposed to the idea of ​​a deep emotional bond.

Psicosociobiológica perspective, jealousy shows a complex behavior that is part of the repertoire of human behaviors. But all that jealousy is known, may at times acquire deterrminados a dimension that exceeds normal limits that would condierados, altering mental health of those suffering and endangering the stability of the couple, in this case impidiedo which satisfy with the purpose for which it would be evolutionarily designed.
