Love is not in the air as you may have been led to believe. It is also not in Hallmark greeting cards, a bouquet of expensive and fragile roses. Nope, the researchers have the answer (yet again) and Love is in your genes. Not your Calvin Kleins , True Religions, or Not Your Daughters Jeans, but in your heredity. Basically, we are attracted to our opposites, particularly those with opposite immunities and we find them with our noses.

The researchers found that a group of genes known as MSC ( major histomcompability complex) are more typically opposite to each other in mates, probably due to the fact that in earlier days, "it was necessary to reduce 'inbreeding'. The MSC gene family is known to affect immunity and scientists believe that it affects fertility as well. Choosing people with opposite MSCs means that there is a greater likelihood of enhancing future children's ability to fight infections and can possibly be found in a person's scent. Basically, a kind of natural selection.

The results seem to be in the preliminary stages- the researchers "expect to find that cultural aspects play an important role in mate choice." Come on, seriously, really, do you think so? I wonder how they will factor in those results and how they will play out on the whole. Namely, what do they think is more important? Gene selection (when people subconsciously look for others who are opposite to them in the gene pool based on Immunities) or a person's socio-economic status?  Or does a person automatically sort out possible mates from their own socio-economic status based on the gene pool natural selection.
