Mother or father, revealed by intelligence to children

A category of genes known as the “conditioned” is believed to be working only when coming from the mother in some cases and from the father in other cases. Intelligence is believed to be among these conditioned genes that must come from the mother.

Lab studies using genetically modified mice found that those with the most doses of mother genes developed heads and larger brains but had smaller bodies. The ones with the biggest doses of my father's genes had a small brain and a large body.

According to research published by The Independent daily, researchers identified cells containing only genes of mother or father in six different areas of the brain of mice that controlled various contemplative functions, from dietary habits to memory.

Father's genes were accumulated into parts of the Limbic system, which relates to such functions as sex, food, and aggression. But scientists found no father's cell in the cerbral cortex, where much of the advanced conjitive skills are located, such as reasoning, thought, language, and planning.

Worried that people may not be like rats, scientists in Glasgow decided to undertake a human study. So their theories confirmed when they interviewed 12,686 persons between the ages of 14 and 22 every year since 1994. Despite taking into consideration various factors -- from the education of participants -- to their race and socioeconomic status -- the group of experts found that the best intelligent prognosis -- was the mother's IQ.

However, research makes it clear that genes are not the only intelligent determination. Only 40 per cent to 60 per cent of the intelligence is hereditary, leaving the rest to the environment.

But experts have also found that mothers have a very significant role in this non-genetic part of intelligence. Some studies suggest that a strong bond between mother and child is closely linked to intelligence.

Scientists at Washington University found that a strong emotional attachment between mother and child is the key to developing certain parts of the brain. In these conclusions they came up after analyzing a group of mothers associated with their children for 7 years and finding that children who had had had emotional support and had been fulfilled by intelligence had committed 10 per cent larger than children who had been more emotionally distanced from their mothers. Hippocampus is the brain region associated with memory, learning, and responding to stress.

A strong bond with the mother is thought to give the child a sense of security that allows him to explore the world and have the confidence to solve problems.
