Read this article, Women's attraction may lie in immune sytem DNA on m24Salud. Researchers from the University of Western Australia made a DNA study with 150 college students and they found that ‘the secrets of attraction are hidden in immune system genes that we inherit from our parents’.
Scientists can not ensure ‘why the strength of the immune system influences the women success in relationships’.
Furthermore they said that neither can fully explain “the relationship between the sweat, and the irresistible genes, but there is a clear possibility that there are clues in the genetic constitution of the women immune system’.
The more varied a woman’s histocompatibility, or MHC, genes are, the more attractive she appears to the opposite sex.
Another theory is that women with varied MHC genes could be more outgoing.
“It is possible that MHC-diverse women have more sexual partners because they actively seek more partners, rather than because males prefer diverse partners,” wrote the researchers.
Relationship expert Lauren Mackler says parents may affect how successful a woman is at finding a boyfriend – but not necessarily because of genetics.
“We are invariably attracted to people based on how familiar that person is to us from childhood,” says Mackler, author of “SoleMate: Master the Art of Aloneness & Transform Your Life.”
“As human beings, we are always seeking homeostasis, or balance, and looking for the parts of us that got lost as we grew up and had to adapt to the family system. So we’re attracted unconsciously to the people who embody these traits. We are looking for our other half and may not always find him.”
