Found a genetic predisposition to laziness

The results of American scientists from the University of Missouri studies have shown that laziness may be due to genetic predisposition. More detailed results of the experiment are published in the American journal of physiology. For evidence of the impact of genes for predisposition to laziness, scientists Frank Booth and Michael Roberts began to multiply rats, some of which was extremely hardworking, and the other part is extremely lazy.

To this end, they were placed in rodents spinning wheel and forced them to run. Each rat was running a total of 6 days, and during this time, the scientists measured how willingly she did. After carrying out such sampling, the researchers crossed 26 industrious rodents between itself and the same thing they did with 26 lazy individuals. After changed to 10 generations of rats, the researchers conducted a similar experiment. As it turned out, the descendants of the industrious rodents continued to remain the same as their ancestors: they ran with the same intensity 10 times longer than their lazy relatives. When the us carried out a comparative analysis of the levels of mitochondria in the cells of rodents, and also made the sequencing of their RNA.

According to Dr. Roberts, they were found more than 1,700 different genes in one of the parts of the brain. 36 genes of these numbers can be the determining factor in the predisposition to motivate physical activity. Scientists plan to continue their experiments in order to determine how much influence each specific gene on motivation. Scientists also noted that the obtained results will help to identify additional causes of obesity in humans.
