A Study Has Proven That Intelligence Comes from Mothers, Not from Fathers!
A recent genetics study has shown that the intelligence comes from the female X chromosome. Moreover, this type of chromosome has over 1,000 genes. Many of these genes affect your perception level.
Until recently, experts thought that both parents are equally responsible for their kid’s intelligence. The study has been found both disputable and correct at the same time.
Many studies have found that genetics is not a simple field of research. It is recommended that people approach these findings from an objective point of view.
Here Is How Both X and Y Chromosomes Function:
A chromosome is actually a thread-like formation that possesses protein and nucleic acids. They transfer and store genetic information. Everyone has 1 pair of chromosomes in every single cell of their body. The males carry 1 X and 1 Y chromosome, whereas the females carry 2 X chromosomes.
Additionally, the genetic feature of gender-specific genes, are either deactivated or activated. This depends on the specific selection as well as genetic properties. In addition, the deactivated genes will not affect genetic development, whereas the activated genes will do so. This means that the paternal genes will be deactivated in case one characteristic is affected through the mother. This also means that the maternal genes will be deactivated in case one characteristic is affected through the father.
In fact, there is a greater chance for females to have an effect on the cognitive ability, because they have 2 X chromosomes, whereas males carry only 1.
Moreover, intelligence is considered to be a gender-specific gene that comes from the mothers. Researchers actually used mice that were genetically modified in order to examine this theory. They concluded that subjects treated with maternal genetic chromosomes had an abnormally greater brain and skull, but a smaller body. On the other hand, subjects treated with greater paternal genetic chromosome amounts developed a smaller brain and skull, but a greater body.
What’s more, researchers also did another fascinating research, such as finding 6 brain areas that possess exclusively either paternal or maternal genes.
In another study, researchers from a Scottish government agency followed 12,687 people between 14 and 22 years of age. They interviewed subjects and observed the way their intelligence developed, considering their ethnic and educational backgrounds. They found that a mother’s IQ is the most powerful indicator of intelligence.
That’s why mothers have a great impact on their kid’s cognitive capacity. But, it isn’t actually just due to genetics. Nurturing and nutrition can also affect a kid’s intellectual development throughout their lives. Mothers play a role in the kid’s intellectual development, which means that your mother gave you so much brain power.
Children inherit their intelligence
from their mother not their father, say scientists
A mother's genetics determines how clever her children are, according to researchers, and the father makes no difference.
Women are more likely to transmit intelligence genes to their children because they are carried on the X chromosome and women have two of these, while men only have one.
But in addition to this, scientists now believe genes for advanced cognitive functions which are inherited from the father may be automatically deactivated.

A category of genes known as “conditioned genes” are thought to work only if they come from the mother in some cases and the father in other cases. Intelligence is believed to be among the conditioned genes that have to come from the mother.
Laboratory studies using genetically modified mice found that those with an extra dose of maternal genes developed bigger heads and brains, but had little bodies. Those with an extra dose of paternal genes had small brains and larger bodies.
Researchers identified cells that contained only maternal or paternal genes in six different parts of the mouse brains which controlled different cognitive functions, from eating habits to memory.
Cells with paternal genes accumulated in parts of the limbic system, which is involved in functions such as sex, food and aggression. But researchers did not find any paternal cells in the cerebral cortex, which is where the most advanced cognitive functions take place, such as reasoning, thought, language and planning.
Concerned that people might not be like mice, researchers in Glasgow took a more human approach to exploring intelligence. They found the theories extrapolated from mice studies bear out in reality when they interviewed 12,686 young people between the ages of 14 and 22 every year from 1994. Despite taking into account several factors, from the participants education to their race and socio-economic status, the team still found the best predictor of intelligence was the IQ of the mother.
However, research also makes it clear that genetics are not the only determinant of intelligence - only 40 to 60 per cent of intelligence is estimated to be hereditary, leaving a similar chunk dependent on the environment.
But mothers have also been found to play an extremely significant role in this non-genetic part of intelligence, with some studies suggesting a secure bond between mother and child is intimately tied to intelligence.
Researchers at the University of Washington found that a secure emotional bond between a mother and child is crucial for the growth of some parts of the brain. After analysing the way a group of mothers related to their children for seven years, the researchers found children who were supported emotionally and had their intellectual needs fulfilled had a 10 per cent larger hippocampus at 13 on average than children whose mothers were emotionally distant. The hippocampus is an area of the brain associated with memory, learning and stress response.
A strong bond with the mother is thought to give a child a sense of security which allows them to explore the world, and the confidence to solve problems. In addition, devoted, attentive mothers tend to help children solve problems, further helping them to reach their potential.
Of course, there's no reason why fathers can't play as big a nurture role as mothers. And researchers point out that a whole array of other gene determined traits - like intuiton and emotions - which can be inherited from the father are also key to unlocking potential intelligence, so fathers - don't despair.
