An interesting spin on typical online dating websites has recently come about. The website SingldOut requires members to submit a DNA swab for testing. The samples are forwarded to a laboratory and are tested for two genetic markers. These genetic markers are then posted to the members profile and compared to other users.
One of genetic markers tested is the serotonin reuptake controller, which is responsible for how people handle negative and positive emotions. The other genetic marker relates to the genes influencing a person’s immune system.
However, through the use of DNA test kits, there is another layer added and better matches may be the result.
Genetics and Attractiveness
Other research studies have explored the genetic mystery behind facial symmetry and body scent and how they relate to attraction between women and men. Researchers found women were more attracted to the body scent of males who had a different type of gene section within the DNA called Major histocompatibility complex or MHC. MHC encodes the proteins dealing with individual body odor and deals with the immune system. It is thought human beings are attracted to others who have a dissimilar MHC section than they do, in order to avoid inbreeding.
What are the social effects of these studies?
What people perceive as attractive will vary. When someone is perceived as “beautiful,” then it is believed they have many other positive attributes which will make them even more desirable.
However, in the quest for beauty many women and men have resulted to cosmetic surgery to make themselves more appealing.
To be perceived as attractive is one thing, but to have attraction for someone else influenced by DNA is an entirely new concept. Beauty is only skin deep and apparently genetics and DNA play a more important role than anyone ever realized. It will be interesting to ponder everything we already know about attraction and how the traditional model of what it is based upon may now change due to all the ongoing studies focusing on DNA.
DNA and Attraction: The Future
It is very important for medical researchers to understand how DNA similarities can influence mating, because scientists studying genetics and evolution cannot assume that genes randomly mix. More studies are needed to uncover the complexities of DNA and how it influences our choice of spouse, but one thing is for certain the results of this study are only the first step in uncovering more interesting and eye-opening information.
