As Brittany Barreto was developing and promoting her DNA-based dating app, Pheramor, that can establish compatibility in prospective couples using a certain string of genetics, she made some couples very jealous. While not single, they wanted to know the compatibility they have with their partner.

"For every single we connected with through Pheramor, there were at least three couples that wanted to complete the DNA swab to find out their compatibility," she says in a news release.

Now, Barreto and her team, which now includes acclaimed relationship expert Laura Berman, have developed WeHaveChemistry, a series of tests and DNA analysis that can give couples a look at their compatibility. And, WeHaveChemistry has taken it a step further to include more than just DNA in the report.

"The team is very excited about WeHaveChemistry," says Barreto in the release. "We've done our research and carefully crafted two reports: the socioemotional analysis and the DNA report. All couples will receive both reports to analyze their physical and emotional chemistry—which we refer to as their 'Love Alchemy."

The results aren't categorized as good or bad, and there's no score determined for couples — the findings are meant to be used to enhance the relationship and as a guide for navigating the trials and tribulations that often come with monogamy.

"The most important way for couples to ensure that their relationship stays strong is to both play to their strengths and to be honest and curious about their areas for growth," says Berman in the release. "We all have areas where we need to stretch a little, both as partners and as people, and couples can apply the findings of the SEA to their relationships and begin growing right away. In addition, the SEA identifies where we are strongest, what we should celebrate and honor, and the areas which we can rely on as a firm foundation when times get tough."

The process goes as follows:

• Couples complete the DNA kit.
• Each person takes the socioemotional analysis quiz, which analyzes emotional intimacy, physical connection, purpose, and future vision. The quiz will identify the person's strengths.
• Each person receive their DNA report, which assesses sexual chemistry based on genetics.
• The two aspects — the DNA report and the quiz results — are combined to predict and guide chemistry.

The way genetics affects attraction is completely subconscious and instinctual, dating back to primitive times.

"The science behind attraction based on your DNA is that people are attracted to one another when their immune systems are different — opposites attract is biologically true," Barreto says in a previous InnovationMap article. "When we were cavewomen and cavemen, we didn't know who was our uncle and who was our cousin, so we used our nose to figure out who is genetically diverse compared to us. If you're genetically diverse, then you're probably not my relative, and therefore we'd have healthier children."

Of course, nowadays, there are many more factors that go into compatibility and both Pheramor and WeHaveChemistry have included that in their assessments.

The DNA kit has swabs and information for two people and is sent through the mail.
