Scientists have recently found that the intelligence comes from the female X chromosome, which has more than over 1,000 genes, many of which influence the perception level.
Up until now, it was believed that both parents contribute to the intelligence of the child, and this is not completely untrue. 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.
A chromosome is a thread-like formation that has protein and nucleic acids, which transfer and store genetic information. Every single body cell has a pair of chromosomes, and while men carry 1 X and 1 Y chromosome, females carry 2 X chromosomes.
The genetic property of gender-specific genes are either deactivated or activated, depending on the specific selection and genetic characteristics.
Moreover, while the deactivated genes do not influence the genetic development, the activated genes do so. Therefore, in case the mother impacts a characteristic, the paternal genes are deactivated, and vice versa.
Yet, as women have 2 X chromosomes, the chances are that they will affect the cognitive abilities of the child.
Intelligence is considered to be a gender-specific gene that comes from the mothers, and researchers have found that genetically modified mice treated with maternal genetic chromosomes had an abnormally greater brain and skull, but a smaller body. On the other hand, the ones treated with greater paternal genetic chromosome amounts had a larger body but developed a smaller brain and skull.
Additionally, researchers found 6 areas that contain exclusively either paternal or maternal genes.
Another Scottish study showed that a mother’s IQ is the most potent indicator of intelligence.
However, it is a fact that the intellectual development of children is also affected by nutrition and nurturing, but mothers undoubtedly play a huge role in the intelligence of their child and the power of its brain.
“Intelligence is complicated. While maybe half of our intelligence as we currently define and measure it is inherited, that proportion is in turn fractured into many many genetic variants scattered across our genomes. These variants operate together in various ways to form what we view as intelligence. And each of those fragments of heredity that contributes is itself subject to a host of environmental factors, both in its immediate molecular world and inputs to the whole organism, that will influence function. And that influence continues after birth as an ongoing mutual interplay of gene variants and environment. It’s layer upon layer upon layer of interacting pieces.”
