That "opposites attract" it is a myth. Scientific studies have shown that in order to start a stable relationship, the lure of the unknown, it does play an important role in the passionate encounters, gives way to security transmitted affinity characters. This theory transcends the merely psychological, as the resemblance between the partners reach even the molecular level. According to a remarkable work carried out by the University of Colorado, people tend to choose romantic partners who possess DNA similar to yours.

Previous research had already shown that individuals are likely to be paired with other similar characteristics with aspects such as religion, age, race, income, type of body and education. Although many of these qualities are phenotypic traits, that is, that are linked to DNA, this is the first time that a direct influence of our genetic material is corroborated in selecting a partner for life.

For this end, scientists examined gene sequence 825 US couples, especially polymorphisms of a single nucleotide, as are areas commonly differ between humans They constitute 90 percent of all genomic variations. The results showed that there was a greater similarity between the DNA of the beloved that between this and the rest of the individuals in the sample. The researchers also compared the magnitude of genetic similarity with the magnitude of a widely studied phenomenon, the similarity for education. In this regard, they noted that the preference for a similar genetically boyfriend was three times less than the preference for reasons of study.

This finding paves the way for future investigations into a possible genetic similarity among friends and also highlights again the influence of the chemical in romantic love.
