Parental genetic role is not equal to exercise ability or follow mother

"He likes to spit anywhere, it's up to his dad!"

"Except for her nose, she looked like her mother carved out of a mold-the nose is obviously like her dad

As the children grow up, similar words are endless

So, from a genetic point of view, who is the father or mother who is more responsible for shaping us personally?

According to a report from the American Fun Science website on November 1, researchers said that there are two explanations for this problem: From which parent the child inherits more genes? Or which side’s gene contributes more? Regardless of the explanation, scientists generally believe that the answer will not be exactly half of one person-50/50

Athletic ability or with mom

Our athletic ability may follow our mother

The researchers explained that it is well known that genes are located on a DNA strand formed by 23 X or Y chromosomes

But the cell actually contains another chromosome hidden inside the mitochondria! A paper published in the journal Physiological Genome in 2011 stated that mitochondria provide energy to cells and play an important role in exercise and aging

Some studies have shown that mitochondrial DNA from mothers plays a key role in our exercise endurance

In addition, a series of studies have found that mothers play an important role in the inheritance of this gene, and only the mother's exercise ability can better predict the child's exercise ability

"Imprinted" genes are important

But some people may not care about which of the parents contributes more genes to the child, and they are more concerned about which of the parents contributes more genes

The researchers explained that, in fact, most of the superficial differences we see between people cannot be attributed to the genes themselves, but to a series of chemical "switches

Researchers say that these "switches" will completely turn off certain genes from the father or mother-a phenomenon called "imprinting", and these patterns will be passed on from generation to generation

An article published in the journal "American Public Library of Science Genetics" in 2012 stated that most studies have shown that there are 100-200 "imprinted" genes in the human body

It's complicated to be like a father or like a mother

So, does the phenomenon of "imprinting" bias gene expression toward the father or mother? Scientists have not yet reached an agreement on this

Andrew Ward, a geneticist at the University of Bath in the United Kingdom, said that there is evidence that the number of genes "imprinted" by the maternal line is the same as the number of genes "imprinted" by the paternal line

However, Ward also said that because the "imprinting" phenomenon occurs on relatively few genes, and the number of these genes from the father or mother may be the same, "imprinting" does not determine whether someone is more like a father or a mother.

Even if the "imprint" gene expression is biased towards the father or mother, it does not necessarily make the individual more alike

Chu En said: "You can say that my gene expression is thanks to my parents, but it is quite complicated to say that I am more like a father or a mother
