To such conclusions scientists came as a result of the experiment, during which 437 beagle dogs were to open the container with refreshments. The researchers wanted to know whether the animals to seek assistance from a stranger, who was also in the room.

According to the results of the experiment were selected 95 dogs, most prone to interaction with the person, and 95 individuals who have shown independence and did not ask for help.The researchers took DNA samples from the animals for analysis and comparison of individual genetic sequences specific to each of the two groups of dogs.

As a result, the researchers were able to identify five genes that may be responsible for the dog and human relations. In this case four of them are related to human - in particular, mutations in these genes to increase the risk of development of social disorders.

Scientists emphasize that the contribution of genetics to the friendly behavior of dogs is about 30%, but the animal is influenced by other factors, including education.
