It is estimated that between 40 and 60% of intelligence is hereditary .In this case, when we talk about intelligence, we refer to the ability to solve problems Recent studies seem to have shown that intelligence is inherited from the mother .Apparently the maternal genes focus on the cerebral cortex and the paternal go to the limbic system .Let's get to know the research!
Is intelligence inherited from the mother?
Forbes magazine, among other media, echoed the news in the Web Second Nexus, which relates intelligence to the genes we inherit from our mother.We summarize the news.
The first studies in the field of genetic inheritance and intelligence were carried out in the decade of the 80 at the University from Cambridge.Through a series of experiments with mice the existence of genes called «conditioned» was discovered.These are activated when they come only from the father or mother .Intelligence is one of those genes and is activated, apparently mostly, when it comes from the mother.In a laboratory test done with mice, when the maternal genes were increased, the mice had the largest heads and the small body , while if those of the father were increased, the head was smaller and the body larger.The researchers identified groups of maternal and paternal genes in different parts of the brain of the mice and these conditioned different congnitive functions.The paternal genes were found in the hypothalamus, preoptic area or tonsil, for example, and these areas are related to the limbic system that basically controls survival functions such as sex, nourishment or aggression.In the cerebral cortex, however, they did not find paternal cells, and that is where cognitive functions such as thinking, intelligence, planning or language occur.
In subsequent investigations it was identified that Intelligence genes mostly come from the X chromosome and, as scientists like Robert Lehrke have explained, since the woman has two X chromosomes , the chances of transmitting the related genes with intelligence it duplicates.
Although intelligence , considered as the ability to solve problems, is genetically determined mostly by the mother , ant and any situation that involves rational thinking is also involved in the limbic system .It provides intuition and emotions, contributions influenced by the genetics of the father.Since the brain functions as a whole, both maternal genetics as the father are involved in any act of thought.In addition, we must not forget that genetically only 40 to 60% of intelligence is inherited, therefore, a significant percentage depends on other factors such as stimulation, the environment or personal characteristics.
What do you think about the news? Do you think that indeed, intelligence is inherited from the mother?
