Wikipedia credits it with starting the field of genetic matchmaking.Why humans have pheromones, when so many other animal species do?But couples with similar variants would be better off if one of them needs a blood transfusion, bone marrow transplant, or part of a liver.
A more questionable application of DNA testing is in “relationship science,” something I learned about a few weeks ago when a reporter from asked me about it.
And so I perused the website of the “leader in human genetic compatibility.” The company offers tests for four genes.
Plus the HLA genes are so involved in biological compatibility that I suspect they indeed have something to do with scent and pheromones.
But do we need a DNA test to tell us when a potential date stinks? That’s one characteristic we can’t yet inspect on our electronic devices.
Knowing one’s HLA type is not without value, but its hard to say whether one should seek a mate with a different or similar profile.
