Dating site compatibility test
Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.
These people will have dates on a regular basis, and they may or may not be having sexual relations.
'With online dating, you have socioeconomic factors people try to match on — religion, how much you make,' Ron Gonzalez, co-founder of Instant Chemistry, told USA Today.
According to research by Instant Chemistry, the maker of the testing kits used by Singld Out, there is a strong correlation between people in long-term relationships having different versions of the serotonin genes and different immune systems.
The tests referenced on the website include an experiment at a Swiss University where males were asked to wear the same t-shirt for two consecutive nights.
The site, Singld Out.com, works by mailing out DNA testing kits to their customers, who then spit in a tube and send it back.
The tube is then sent to a lab, where it is tested for the presence of two genetic markers.
