Are you a cat or a dog lover? Perhaps this is genetic. Whether a person decides, with a pug, a Terrier or a poodle to live together, is also influenced by its genetic material, found Swedish and UK researchers from the Uppsala University and the University of Liverpool now.

The scientists, who published their findings in the journal Scientific Reports, interviewed for 35 000 Swedish pairs of twins. Came out: Identical twins are genetically identical, had very often both a dog - or both did not want. Fraternal twins, not more of the same from the genome than other siblings, were in this matter only half as likely to agree: often the had had a twin, a dog, and the other not. At a minimum of every other dog owner, the end, the researchers concluded, it will be the genotype of an influence on the fact that he lives with a four-legged friend together.

The scientists suspect that this is also due to an innate greater tendency to like taking care of animals. Explore you want to now, what are the genetic variants for the love of dogs essential - and the context in which these other genetic characteristics, but also allergies, for example against dog hair.
