THE RECORD -- Mar 10 -- For Eric Holzle, the founder of ScientificMatch, the quest for romantic compatibility begins not in the heart but in the cheek. Clients submit a cheek swab which is assessed for genetic compatibility with other clients. This stretch of DNA, known as the major histocompatibility complex (MHC), plays a fundamental role in the immune system. The immune system, in addition to fighting off disease, is the source of our sex appeal. The ScientificMatch membership costs $1,995.

Mark Brooks: I tried a 23andme.com DNA test recently. It told me I had a higher than average chance of developing diabetes, and a less than average chance of developing heart disease. It cost $1k. In time we'll see DNA tests enter the mainstream and novelty social networking sites will seek to utilize the 'identity' information that is locked up in our genomes. In 30+ years will dating sites include peoples DNA 'identities' as a standard part of their matchable profiles? Your comments please.
