Could the same now be happening to love and lust, the most mysterious and magical of all human emotions?
Sort it out But genes play a role in many of the traits that people use to sort themselves into pairs, including geographical origin, intelligence and more.
The researchers attempted to account for these factors by controlling for geography, after which the genetic results still remained.
While genetics seems to play some role in human sexual attraction, it clearly is not the only, or even predominant, factor determining human mate choice.
Singld Out claims that genetic tests can identify up to 40 percent of the chemistry of attraction between two people.
The results were limited to opposite-sex, non-Hispanic white couples, and the study represents only a "first step" in teasing out the genetics behind mate-choosing, the researchers wrote.
Questions remain, such as whether people's genes help shunt them into environments — college, for example, or trade school — where they happen to mix and mingle with others of similar genetics, which could explain much of the effect.It has long been known that other mammals, such as mice, selectively mate with partners having different genetic variants of their MHC genes, which control immune responses.A leading hypothesis is that such “disassortative” mating will produce offspring with greater diversity in their MHC genes that will protect them against a broader range of pathogens.Given that all mammals display similar genetic mechanisms, one might expect a similar genetic attraction to exist in humans, albeit within the context of the greater complexity of human relationships.Indeed, a 1995 study found that single women, asked to smell and pick from sweaters worn by men, were disproportionately inclined to pick one worn by a man with different MCH alleles from their own.Instant Chemistry and Singld Out are not the first to promote genetic testing to determine romantic compatibility.
