Hey, Girl... Nice Genes

According to a new study from the University of Colorado Boulder that probably shouldn't be trusted because EVERYONE THERE IS HIGH(!!!!), human narcissism may extend to the genetic level. The study found that people are more likely to pick mates with similar genomes. Using 1.7 million single-nucleotide polymorphisms, researchers compared the DNA of married people to randoms and found a preference for a genetically similar spouse. They call this effect 'genetic assortative mating', and say it's approximately a third as strong as 'educational assortative mating' — the phenomenon of people with similar educational backgrounds pairing off.

 

So what does this all mean? Has Alabama had it right all along? Not likely, kissing cousins! It just means that other scientists may need to revise statistical models that assume random genetic mating. Also, it means the BioPop DNA Portrait can now be used for completely non-scientific compatibility testing. Hooray!
