Recent surveys shows that children inherit intelligence from only one parent
There is a lot of speculation about which parent the kid will look like, including whether or not it will have the eyes of the mother or the eyes of the father. Comparisons are made from every angle, but what the scientific literature has to say is that intelligence is something that is inherited from one’s mother by one’s offspring.
According to study, a child’s intellect can be predicted based on their mother’s genes, while a father’s genes have no bearing on a child’s intelligence.

The reason for this is because the genes for intelligence are carried on the X chromosome, and women have two of these chromosomes, whilst men only have one of these chromosomes. Therefore, women have a greater chance of passing these genes on to their children.
Studies in a laboratory using genetically engineered mice discovered that those with an extra dose of the maternal gene produced larger heads and brains but smaller bodies. It is believed that intelligence is one of the genes involved, which must start from the mother. Those individuals who received an additional dose of their father’s DNA had larger bodies but smaller brains.
The researchers isolated cells in six distinct regions of the mouse brain that are responsible for cognitive skills such as memory and feeding habits. These regions are controlled by genes inherited from either the mother or the father.

There was an accumulation of cells in the areas of the limbic system that are involved in processes such as sex, hunger, and aggression that contained the DNA of the father. However, the researchers were unable to locate any father cells in the cerebral cortex. The cerebral cortex is the region of the brain that is responsible for the most complex cognitive processes, like as reasoning, thought, speaking, and planning.
However, studies have shown that genetics is not the only factor that determines a person’s level of intellect. It is believed that only 40 to 60 percent of a person’s IQ is inherited, while the rest is influenced by their upbringing and experiences.
