“Opposites attract” is a common
phrase applied to the realm of dating, however, our genes may dictate the
contrary. Several universities conducted a joint analysis of mating patterns
and found that individuals have a tendency to have partners with similar DNA.
This is called assortative mating. The similar genetic ancestry is a stronger
factor that socioeconomic status or educational levels when choosing a mate. The
genetic ancestry was so similar that the average couple shared the genetic equivalence
of third or fourth cousins.
One could
argue that assortative mating is common because individuals are ethnically or racially
similar tend to live in the same population. It is obvious that we have some conscious
control over who we choose to date. Some are more selective than others. Some
show a similar trend while others don’t. Ultimately, it’s neither solely by
choice or genetic predisposition, but a comprehensive spectrum.
