Medical science is struggling to find the Left-handed genes factor.
As per a study from Australia: Despite the tremendous success of medical science, we are still unable to understand why the majority work directly. Why are some people left-handed and why can’t they write with both hands?
Now experts have studied 1.7 million people to answer this question and noted that there are 41 genes that probably make people work right and especially with the left hand.
Experts have studied the genes of millions of people with brain activity and tried to find out the genetic cause of the right or left hand. The right or left handwriting process can also affect the brain structure, says research associate geneticist Dr. Sarah Medlin.
Our research shows that there are 41 genetic changes that can make someone a right-handed person, while the other seven genes are found that form the right and left-handed at the same time. But remember that they only play 12% of all genes in this case. This means that many other factors can be useful in the right or left-handed ones and we don’t know about it yet.
Environmental factors may also contribute to this,” says University of Queensland geneticist David Evans. The left hand is more active than the right or left hand from the beginning when it comes to injury, play, writing, or musical instrument.
Data from British Biobank has been taken for this experiment, while the full details of this have been published in the journal Nature Human Behavior.
