How DNA influences your romantic decisions.

Two strangers spitting on a test tube is not the most traditional start to a love story.

Cheiko Mitsui had been searching for love for over 10 years when she discovered the union of couples through DNA.

The 45-year-old woman, resident in Hakodate City, on Hokkaido Island, Japan, had divorced at 35 and felt unfortunate in love.

“I met several people at parties, through friends, and I also signed up for an agency to form relationships, but failed to find the right people.”

Later, Mitsui met Cheiko Date, a matchmaker who claims to have joined 700 couples over 20 years..

In 2014, he began working with the Swiss company GenePartner, which says that its genetic testing can serve as a “complement” to the union of couples, in a process that was questioned by experts consulted by the BBC (as explained below).

“It's important to have both sides; one of them is biological compatibility or what we call chemistry,” says geneticist Tamara Brown, one of the founders of GenePartner. “The other side is social compatibility. Both have to work for the relationship to be successful.”.

To achieve these results, a swab is extracted from the inside of the customer's cheek. From the collected material, the genes of the so-called human leukocyte antigen system are analyzed.
