Singld Out is an online dating service that operates via the professional networking site Linked In and uses Instant Chemistry’s genetic testing results to match its members.DNA results become part of each user’s profile, and members can search for and evaluate potential matches based on their genetic compatibility.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.You would be wrong to assume that you cannot access a dating website without holding a full membership.In 2009, "Online Dating Newsletter" estimated that more than 20 million people a month visited online dating services.Applying a similar concept are “pheromone parties” in which singles sniff well-worn T-shirts worn by members of the opposite sex to facilitate biological matches based on pheromones, the elusive compounds of attraction.Unlike some direct-to-consumer genetic testing companies (such as those claiming to offer genetically tailored nutritional supplements, which have been subject to enforcement by the Federal Trade Commission for deceptive claims), there is some legitimate science behind the new DNA-matching dating websites.
Similarly, a 2006 study found that the more differences in MHC genes between a romantic couple, the more likely the female partner was to be sexually satisfied and committed to her existing relationship.
Yet, as noted above and as is common for most genetic research, especially as it relates to complex human behaviors such as love and romance, the data supporting genetic attraction is highly inconsistent.
A large number of studies, involving different experimental methods and populations, have now been reported, and they give discordant results.
Testing for STG variation might be genetic compatibility services’ best bet, because if you or your partner has two copies of the short variant of that gene, it may result in a heightened response to either positive and negative influences on a marriage.
This might argue for a heightened awareness of the importance of keeping a relationship on a positive keel.
