As we know, genetics can play a role in the health of individuals, whether in the appearance of certain diseases such as autism or cancer, but also in behaviors such as the sleep Where the laziness. It is even involved in the predisposition to happiness, according to some studies.
A new study from the University of Edinburgh in Scotland establishes a link between genetic heritage and intelligence. In other words, the more our genes are different, the more we would improve our cognitive functions. This genetic diversity would also make it taller, according to the researchers.
In the journal Nature, the 25 researchers who collaborated on the study explain that they have dissected the DNA of 354,224 individuals from Europe, Africa, Asia and Southeast Asia. Objective of this painstaking work: to determine the influence of genetics on sixteen traits linked to the health of the participants.
“We did not use any” pedigree “data, specifies James Watson, co-author cited by Science and the Future. We measured homozygosity or heterozygosity directly by analysis of the genome”. Clearly, the Scots wondered if being heterozygous, that is to say having two alleles (variants of this gene) different from the same gene changed something compared to being homozygous (two identical alleles on the same gene).
Verdict: being heterozygous would allow you to rise intellectually and gain height in the true sense of the word. The lower the homozygosity, the higher the height and cognitive ability of the individual. Conversely, the higher the homozygosity, the lower the size and cognition of it “, summarizes the study.
