Genetic factors have great impact on the features of children. This relationship is not only evidenced in aspects such as its physical appearance or its character, but also in elements such as its intellectual development.
Surely he has ever heard that they tell you or a relative “You are as intelligent as your mom” or “you took out your dad’s intelligence,” but has you ever wondered if this may be true?
Well, this question has an answer based on scientific studies. And according to what is known, the characteristic is not random, but There is a more influential parent in the development of this.
According to an investigation with animal tests and published in the Psychology blog ‘Psychology Spot’ and cited by ‘The Independent’, the intelligence of children It is more inherited from the mother.
The experiment was carried out with mice to which the genetic load they contained from their father and mother were modified. The results showed that rodents with more maternal DNA had larger brains and smaller bodies, While if the genes were more paternal, the opposite happened.
Why is the mother who transmits intelligence?
According to the study, the relationship between the parent and the inheritance of intellectual capacity is due to the activation of genes associated with the X chromosome, that as it is known is contributed by the female sex.
As women have double xx chromosome, that is XX, and men have one, that is XY, it is more likely that children inherit their mother’s intelligence, because while man has a single possibility of transferring it, The woman has two.
The findings of the researchers indicate that if the father transmits the intelligence gene, it is automatically deactivated, since it is about “Conditional genes.” In the event that they come from the mother, they activate and fulfill their normal function in brain capacity.
What genes can the father contribute?
The instinct of survival, food, aggression and the brain zone in charge of emotions, They are some of the paternal genes that can be activated in their children and fulfill their basic functions.
The above shows that The most complex activities As the development of language and the ability of thought, it can be more influenced by the genes that the mother brings to the child.
To take into account
Although there are scientific evidence, it is important to mention that each child can experience changes or alterations in their learning process, depending on what it is the context in which it grows and develops.
For experts, early stimulation, school education and the environment in which most of the time is, They can be conditions for cognitive development.
