SingldOut an exclusive online dating site, claims to be the first to use DNA to link potential partners. The site already connects single professional's using their LinkedIn accounts, but the new DNA feature will test for "biological compatibility" between users as well.
The process is somewhat simple: New members receive an Instant Chemistry DNA kit in the mail, then spit into a tube, and mail it back. They're testing for two markers, to see genes that influence the immune system, and serotonin transporters which are involved in how people react to different emotions.
Instant Chemistry co-founder Ron Gonzalez told USA Today, "With online dating, you have socioeconomic factors people try to match on -- religion, how much you make. This is another layer on top of that so you can better find matches." The co-founder of SingldOut, Elle France, said they were looking to get into the "science behind attraction."
But that layer comes at a price. Membership for SingldOut starts at $199 for three months.
