Does Intelligence Come From Mother Side of the Family
Hello Sehat (The Jakarta Post)

A child's intellect does descend from their parents, merely is information technology true that information technology primarily descends from the mother? What about the male parent?
In China, many pondered to detect the respond subsequently an article appeared on microblogging site Sina Weibo, which stated that genetics from the mother had 3 times more influence in determining the child's intellectuality than from the begetter. The article said, "To determine the intellectuality of a child, nosotros can refer to the mother. For men who consider themselves unintellectual, information technology is recommended for them to find a smarter married woman."
Nonetheless, is it really true? Let's take a wait at the explanation.
The link between the X chromosome and intelligence
Explanation given by the article mentioned above is that the intellectuality traits are carried on past the Ten chromosome (female person chromosome genetic carrier). Withal, information technology does not quote any scientific references or sources for every statement it makes. In the commodity, Satoshi Kanazawa said general intellectuality was known to be inherited and the genes that affected common intellectuality were suspected to be carried by the Ten chromosome. This means that boys inherit their intelligence but from the female parent, while girls inherit their general intelligence from both mom and dad. Therefore, women should be more of an influence on intelligence compared to men.
Si Dayong, a lecturer on Evolution at Jilin University, refutes the claims made in the Weibo article, "Descendants from a certain gender accept nothing to do with Ten and Y chromosomes, but some sort of epigenetic traits [traits that are not caused by changes in Deoxyribonucleic acid sequence, merely more than on changes in the genes expression]," he said. "I oasis't yet plant a certain trait that tin can be dominant from either the mother of male parent."
Research on derived intellectuality
A study published in an academic journal of Beliefs Science in 1982 sees a correlation between parent and child. It has come up to attending that IQ correlation between mother and kid is a trivial higher at 0.464 compared to father and child at 0.423.
"I don't think this small difference is considered statistically significant," said Si. "Other than that, genetic inheritance is something random and complicated, out of a homo's imagination."
Although it has been long believed that heredity contribute to a child's intellectual, yet newer study found that it really lacks contribution than predicted before.
A study in 2013 done by researchers from University of Queensland conducted a Dna analysis and IQ test results from more than 18,000 children from Commonwealth of australia, Netherlands, UK and U.s.. As a result, they found that heredity contributed effectually xx-40 percent from children's various IQ, lower than expected before. Researchers later conclude that at that place is no single gen variant that can strongly predict child's intellectuality, and that intellectuality that is inherited genetically is a cumulative result from different variation of genes.

Zhao Bowen, a researcher at Shenzhen Huada Gene Inquiry Institute, elaborates a finding in a 2014 article at knowgene.com. "To this very twenty-four hour period, no Deoxyribonucleic acid sites directly determines the origin of human intelligence," he said. "Parent's Genetic influence on children's intelligence could exist more than or less, and a child's intellectuality tends to accept a normal distribution bend, with parents inherited intellectuality as a median."
Xu Gelin, a doctor of neurology at Nanjing General Hospital of Nanjing Military machine Command, emphasized in Jinling Evening News Written report published in Nov 2014, that genetic heredity random and complex, and that both parents had various level of influence on the kid's genetics. "For instance, if the female parent has higher IQ, and the male parent has lower IQ, chances are their children will fall in between," said Xu.
This argument acquired a contradiction with what said past Weibo, stating that to determine the intellectuality of a child, we tin can refer to the mother. "Of course, it is well approved that a child with both high IQ parents volition be pretty smart in full general."
Other factors affecting a child'south intellectuality
Dr. Rachel Brouwer from the Psychiatric Department of Utrecht University Medical Center in the Netherlands states that it's truthful that yous can predict a child's IQ, but it'due south based more on the parent'due south IQ rather than changes in their brain on a group level. "So in general, brilliant parents will produce brilliant children equally well. However, this is not absolute, it could be that low intellectual parents turn out to have children with high IQ and vice versa." Dr. Brouwer besides emphasized that the environment contribute an impact to intellectuality, even though it will lessen as the kid grows.
Senior lecturer at Melbourne Academy's Graduate School of Didactics Catherine Scott puts a stronger emphasis to the environs and history. "Children don't only share genes with the parents," she said. "They also share family and environment. This also links closely with their food and their mother's food." (kes)
