Research Reveals: Children Inherit Intelligence from Their Mother, Not Their Father

Will all mothers accept and acknowledge this?

Science—and Dr. Keith Witt—both indicate that human beings inherit intelligence from their X gene, and since this is the feminine gene, it means that mothers are usually more responsible for the intelligence of their children than fathers are. Up until these findings, there was a common consensus that both parents contributed about equally to their children’s intelligence. It’s important to note that genetics is a highly-complex science, and research is continually being overturned by newer research in some cases.

X & Y chromosomes.

Chromosomes are thread-like structures which are comprised of nucleic acids and protein that carry genetic info. Each person has one pair of chromosomes in every cell; females possess two X chromosomes, whereas males have one X and one Y.

“Conditioned” genes.

These are gender-specific, and the genetic properties of conditioned genes are activated and deactivated based on their distinct designation and influence. These genes contain a “tagging” system that is comprised of biochemical material which can trace a gene’s point of origin and determine active or deactivated states within the human body. Activated genes impact genetic development, whereas deactivated genes do not.

Findings & history.

Women are more likely to impact cognition because they have two X chromosomes whereas men possess only one. What’s more, since intelligence is a highly-conditioned gene, the odds of a mother significantly influencing a child’s cognition are even greater. Scientists utilized genetically-modified mice in their studies, and they found that embryonic test subjects that were given predominantly maternal genetic material ended up with larger craniums and brains, and smaller bodies as well. The opposite was true for subjects given disproportionate amounts of paternal genetic material.

Furthermore, no paternal genetic material was found in the cerebral cortex, which is the region of the brain in charge of executive functioning: language, planning, logical reasoning, and advanced thinking. It’s also important to note that in 1984, the University of Cambridge researched brain development (“co-evolution) and genomic conditioning; they eventually found that maternal genetics contribute primarily to thought centers in the human brain, and similar findings have also been realized since. Researchers at a Scottish agency studied a group of 12,686 people between the ages of 14 and 22, and factors from education to ethnicity were closely monitored and evaluated. In the end, a mother’s IQ was revealed to be the most effective indicator of a child’s cognitive abilities.

In addition to what has been analyzed and discussed, nourishment and nurturing of children has also been found to impact intellectual development significantly; it’s vital to note that mothers are often the parents who engage in these activities the most, as well.
