Genetic matchmaking is entering the mainstream. The prospect of meeting and selecting potential romantic partners based upon purported DNA compatibility—until very recently the subject of science fiction from films like The Perfect 46 to independently published romances by Clarissa Lake—has increasingly garnered both scientific and commercial attention. Earlier this year, Nozze, a well-established Japanese dating service, established a DNA Matching Course and hosted a related DNA Matching Party, both first-time offerings in that nation. For 86,400 yen ($790), men are paired with prospective dates based upon 16,000 variations in HLA gene complexes.
