You must have seen a husband and wife couple or the extended family of the couple fighting over who has the physical appearance or the advantages that are passed on to their children? Or does this often happen in your own life?
So, so that you don't fight over it, try reading some references based on research on what genetics are passed down from parents to children. For example, such as the information reported by Sneak Peek which contains an explanation of the following three things that a mother inherits from her child!
Red-Green Color Blindness
As the name suggests, a person with this condition cannot tell the difference between red and green. This condition is bound to the X chromosome in the human body.
If a mother has an X chromosome that carries this red-green color-blind information, then her child will automatically inherit the same condition. Meanwhile, the daughter will not have it unless the father also has a similar X chromosome.
Signs of Aging
Who says aging is only influenced by external factors, such as UV rays, toxins from cigarette smoke, and pollution?
Research from the Karolinka Institute and The Max Planck Institute for Biology and Aging states that a mother will pass on mDNA to her children. mDNA has a significant influence on signs of aging
It should be noted that this part of the cell is only inherited by the mother. Meanwhile, mDNA from the father usually only combines with the mother's cells or destroys itself if they cross paths.
Intelligence
Mother often doubles up as a math tutor, assistant when doing schoolwork, to corrector when homework is finished. However, this is not the scientific reason behind the fact that intelligence is inherited by a child from its mother.
The X chromosome carries the genes responsible for intelligence and social-cognitive abilities. This causes a son to inherit intelligence from the mother.
Eits! It means that a daughter does not necessarily inherit intelligence from her mother as in the case of red-green color blindness, right? Wait a minute!
There are other factors that influence intelligence besides the X chromosome. Research shows that the human brain is jam-packed with mDNA. This is due to the complex structure of the brain and requires a lot of energy compared to other organs of the body.
This explains the second reason why children inherit intelligence from the mother, the exclusive "producer" of mDNA for her child's body. So, no matter the gender, mother is the main intelligence heir for her children!
