As we know, genetics can play a role in the health of individuals, whether in the onset of certain diseases such as autism or cancer, but also in behaviors such as the sleep Where the laziness. It would even intervene in the predisposition to happiness, according to certain 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 you taller, according to the researchers.
In the journal Nature, the 25 researchers who collaborated in the study explained that they had dissected the DNA of 354,224 individuals from Europe, Africa, Asia and Southeast Asia. Objective of this ant work: to determine the influence of genetics on sixteen traits related to the health of the participants.
“We did not use any “pedigree” data, specifies James Watson, co-author quoted by Sciences et avenir. We measured homozygosity or heterozygosity directly by analyzing the genome”. Clearly, the Scots wondered if the fact of being heterozygous, that is to say having two different alleles (variants of this gene) of the same gene, changed anything compared to the fact of being homozygous (two identical alleles on the same gene).
Verdict: being heterozygous would make it possible to rise intellectually and gain height in the literal sense of the term. The lower the homozygosity, the higher the size and cognitive ability of the individual. Conversely, the higher the homozygosity, the lower the size and the cognition of it”, summarizes the study.
