Harvard Geneticist Wants to Develop a Dating App Based on DNA Compatibility – Interesting Engineering


The number of people who are using dating apps is getting increased every day. You can choose the person you want to date now based on their appearance, their interests, their profession, and many other criteria. But have you ever thought of matching with someone based on your genes and the diseases you carry, dominantly or recessively?


If you ever took Biology class in your life, you’d know that dominant genes take precedence over recessive genes. That’s why you came out with brown eyes from your blue-eyed dad and brown-eyed mom; because the brown eye gene is dominant over the blue eye gene.


Some genetic diseases are also caused by recessive genes; such as Isovaleric Acidemia, which is seen in 1 out of 250,000 people in the U.S.A.

geneticist George Church wants to create a dating app which will match users based on the genetic diseases they carry, and the likelihood of not passing the diseases to their children.

In an interview that Church gave to the correspondent Scott Pelley, he said, “You wouldn’t find out who you’re not compatible with. You’ll just find out who you are compatible with.”

Pelley asked, “You’re suggesting that if everyone has their genome sequenced and the correct matches are made, that all of these diseases could be eliminated?”

“Right. It’s 7,000 diseases. It’s about 5% of the population. It’s about a trillion dollars a year, worldwide,” Church answered.


Of course, everyone having access to their genome sequenced isn’t possible yet. Also, even if it was possible, most of the human beings are too emotional to give up on their love just because they have incompatible DNA. However, this system would work like a charm to have the healthiest generations in the future.
