DNA and your partner selection

Individuals with genes for high educational achievement tend to marry , and have children with people with similar DNA, researchers have found.

Humans generally do not choose their partners randomly, but rather mate assortatively, choosing people with similar traits. Among the highest ranking qualities people look for in a potential partner are intelligence and educational attainment, the study said, adding that the choice has a significance at a DNA level.

The findings show strong evidence for the presence of genetic assortative mating for education. The consequences of assortative mating on education and cognitive abilities are relevant for society, and for the genetic make-up and therefore, the evolutionary development of subsequent generations.dna and partner selection

However, assortative mating pattern could increase genetic and social inequality in future generations, since children of such couples are more unequal genetically than those of people who mate more randomly.
