A well-matched couple who is similar somewhere. It is a word to hear frequently that men and women are attracted to each other as much as they have in common. To tell the truth, it seems that not only does it feel just like it, but it is really like genetic structure indeed!

According to a paper published in ScienceDaily, electronic journal PLOS Genetics, it turns out that there are very many couples genetically similar. It is argued that when it develops it will become a genetic element common to the community, reaching what it should be said to be a " common gene " of the region, country and culture sphere .

A research team led by Ronnie Sebro of University of Pennsylvania and others who advanced the investigation thoroughly analyzed "Framingham Heart Study" which tracked the cardiac diagnostic data for residents of Framingham, Massachusetts since 1948. From the 879 couple genome data, are investigating the influence of common ancestors on genetic structure.

The American Society called the melting pot of race. But, mainly in the following go was of this survey the ancestor of a Caucasian couple, Northern Europe, Southern Europe, the men and women of an Ashkenazi system, each is a case that has been married to choose a spouse of the same roots almost became clear that it was. Because of that influence, the genetic structure of each other was very similar, though it was a couple not directly connected with blood. Of course, recently, as the number of couples in different backgrounds is increasing, genetic similarities tend to diminish. However, it may be that the two people who were attracted to each other because of their similar familial environments are more likely to fall in love with a common ancestral genetic structure .
