Studies Reveal That Children Inherit Their Intelligence from Their Mothers

These genes have an inbuilt tagging system

Conditioned genes have a "tagging" system built into them. This system is made up of biochemical materials. This tagging system makes it possible to do two important things: tracing where the gene originated and determining an activated or deactivated state within the body. Genes that are activated will affect genetic development, while deactivated genes will not.

Secondly, if the maternal genes influence the individual's characteristics, then the paternal genes are deactivated. On the other hand, if a trait comes from the paternal genes, then the maternal genes are deactivated. The study of intelligence is based on the mechanisms of the conditioned genes.

The results of the intelligence study and their history

People think that the X chromosome has the most effect on how people think. Theoretically, because women have two X chromosomes and men only have one, women are more likely to change how people think. The theory is about much more than just the number of X chromosomes.

This is where conditioned genes come into play. People think that intelligence is a highly conditioned gene or a conditioned gene that comes from the mother.

Mice were used in an experiment to test this theory

Scientists used mice with changed genes to test their theory in this study. They found that embryos which were given disproportionately maternal genetic material developed craniums and brains that were much bigger than average. However, their bodies were much smaller. Subjects which were given disproportionate paternal genetic material grew bigger bodies but had smaller skulls and brains.

Paternal genetic material was mainly absent in the cerebral cortex

Aside from the size of the brain and cranium, researchers also observed some interesting things. First, they found six parts of the brain that only had maternal or paternal genes. Second, they didn't find any paternal genetic material in the cerebral cortex, which is the part of the brain that controls executive functions like language, planning, logical reasoning, and advanced thinking.
