According to a recent genetics study, our intelligence derives from the female X chromosome.
The X chromosome has a thousand genes, and many have an impact on your level of perception. Until recently, doctors believed that parents contribute equally to their child’s intelligence.This research has been proven both correct and disputable at the same time.
Most studies have proven genetics to be a highly complex field of research. It’s suggested that people approach these studies from an objective perspective. It’s helpful to present a couple of key facts about how X and Y chromosomes work.
A chromosome is a thread-like formation made of nucleic acids and protein. They store and transfer genetic information. Every person has one pair of chromosomes in each cell of their body. The females have two X chromosomes, the males have one X and one Y chromosome.
The genetic characteristic of gender-specific genes, are either activated or deactivated, depending upon the specific selection and, later on, the genetic properties are affected. The activated genes will impact genetic development, while deactivated genes won’t do so. So, if a single characteristic is affected via the mother, the fatherly genes are deactivated. At the opposite side, if a single feature is affected via the father, the maternal genes are later deactivated.
The structure of these gender-specific genes forms a foundation of intelligence research. Women are much more likely to have an impact on cognitive abilities, as women possess two X chromosomes, while men carry just one. There is certainly more to this theory of intelligence genetics than just X chromosomes.
Intelligence is thought to be a highly-gender-specific gene that originates from the mother. Scientists used genetically-modified mice to test this theory.
It was found that embryonic test subjects, which were administered maternal genetic chromosomes, developed an improperly larger skull and brain while developing a smaller body. Subjects treated with larger amounts of paternal genetic material developed a larger body, but a smaller skull and brain. Researchers made other intriguing observations, like identifying six areas of the brain what contain exclusively either maternal or paternal genes.
The University of Cambridge studied brain development and genomic conditioning in 1984. Cambridge scientists concluded that maternal genetics give more material to brain centers. In a study, researchers from a government agency in Scotland followed 12,686 people aged 14 to 22.
Researchers interviewed subjects and monitored how their intelligence developed, taking into factor their educational and ethnic backgrounds. They concluded that a mother’s IQ is the best indicator of high intelligence.
There is a certain fact that can be taken from this, and that is that mothers have heavy influence on their children’s cognitive capacity.
It’s not just because of genetics, in fact. Nutrition and nurturing do influence a child’s intellectual development throughout their lives. Women play a part in the child’s intellectual development. All signs point out that our mothers give us so much brain power.
Thank you to all Moms!
