Some online dating sites rely on a mathematical algorithm to match people. Others are based on pure physical attraction and a quick swipe to the left or right.

But a new online dating site promises deeper compatibility by testing users’ DNA. They say they’ve found the secret to “long-term chemistry” — what makes a relationship last — in people’s genes.

Two companies, SingldOut and Instant Chemistry, are working together to match users based on the results of both a personality test (evaluating “diet habits of a mate, how often they exercise, and so on,” according to a company press release) and a genetic test.

“Through intensive research, scientists have found that long-term relationship satisfaction stems from two constants — your DNA and core personality — and how those match up with your partner’s,” said Sara Seabrooke, a geneticist and chief science officer of Instant Chemistry, in a press statement.

Ultimately, geneticist Ricki Lewis said, the science doesn’t live up to the hype. “Testing for two genes out of 20,000 … is hardly useful — would you select a person to date based on four items on a 20,000 item questionnaire?” she asked. “Even if what those two genes do makes sense, it is simply too little information to have any value.”
