According To Research: Intelligence Is Inherited From Mothers
Scientific studies have shown that our intelligence is inherited from mothers. Read more about the results below.
In today’s society, women have regained reasons regarding gender differences that were previously introduced. As a result, single mothers can provide their children with everything they need.
Mothers also do not have to look for an intelligent man to have intelligent children. According to research, children’s intelligence is in their hands.
Why is it said that intelligence is inherited from mothers?
Theories claim that certain genes – which researchers call “conditioned genes” – respond in different ways depending on their origin. Conditioned genes are only recognized as such when inherited from the mother.
Therefore, when a conditioned gene emerges through paternal inheritance, even if it is the same, it goes unnoticed. The same thing happens with other types of genes that come only from paternal inheritance.
We already knew that intelligence is a hereditary factor, but we did not know the unique origin. It was once thought that both parents had equal influence, which would alternately depend on unknown factors.
It was recently discovered that maternal cells tend to be directed towards the brain.
Previous studies have established that female genes contribute significantly to the development of thought. Since the genes that determine intelligence are found on the X chromosome, it is also possible to come from the father’s intelligence.
But the chances of it being inherited from the mother are greater.
Most genetic diseases that affect cognitive abilities are registered on the X chromosome. Therefore, the chances of the mother transmitting this are also greater as she carries on X chromosomes.
The study
To conduct this research, the researchers tried to create modified rats that had only genes from either their mother or father. The results were unfavorable at first. All the embryos died when they were implanted in the uterus.
This led to a great discovery: There are mother-fused genes that allow for the development of the embryo. There are also paternal genes that are necessary to develop the tissues that make up the placenta.
The researchers have deduced that the significance of these conditioned genes goes far beyond the formation of the fetus. They assumed that brain functions could also be associated with the development of these genes.
They modified some of the genes and experimented with mice whose genetics came predominantly from one of the two parents.
The results were as follows: The mice that had the most maternal genes had larger heads and brains.
On the contrary, those mice with greater paternal genes had smaller brains and heads. Their bodies were not proportionate either; those with larger heads had smaller bodies and vice versa.
They also noted that although the cells from both parents were found in the brain, the cells that came from the father became more concentrated on food, aggression, and overall survival. The mother’s cells were dominated by areas of the brain that control cognitive functions.
Intelligence is not just inherited
It is understood that on average about 40-60% of intelligence is inherited. The rest is developed through stimulation and the environment. Although intelligence is inherited from mothers, it can also help us in other ways.
The intellectual development has a lot to do with the stimuli we receive. The emotional support and security we feel is also important.
Mothers give us space to develop our abilities. Through their secure bonds, we feel more motivated and confident, to explore and keep going.
Mothers urge us not to give up. They teach us to solve problems. This is how we learn to be tolerant of frustrations, as well as always give our best.
The way we relate to our mothers allows development in many parts of the brain. This is shown by the results that intelligence is inherited from mothers.
