DNA Love Connection? Test Uses Genetics to Determine Compatibility


"You can cheat on compatibility, can guess what you're going to find out about yourself if you guess A, C or whatever, but this is actually science," Smith-Adair said.

When the results came in, Blount and Smith-Adair learned that had a 10 percent genetic compatibility.

"They didn't explain this at all," Blount said. "I really want more information about the science here. I don't get what any of these numbers mean."

Blount and Smith-Adair did get a 75 percent emotional compatibility score, a score they thought should weigh more heavily than the genetic score.

Happily married for five years, Maria and Taso Pardalis took the test and learned they had a 75 percent emotional compatibility and, what the company calls, a nearly perfect genetic compatibility of 98 percent.

"It's good to know," Taso Pardalis said. "I'm glad I know."

"Well it's good, also because we have two kids so that means they have a good genetic makeup," added Maria Pardalis. "Obviously I'm very happy."
