From a kind of sense of responsibility towards equality, we often tell ourselves that we are the product, equally, of both parents. But this is not always the case.
But in these circumstances, who should you identify as responsible for those traits you don’t like? What did you inherit from your mother and what did you inherit from your father?
From whom do we inherit color blindness?
In general, if you are a man, you can thank your mother.
The inability to distinguish between red and green is a disorder related to the X chromosome, which affects almost 6% of the male population worldwide, but only 0.4% of the female population.
This is because men inherit only one X chromosome, which comes from their mother, and from there comes color blindness.
Instead, if you are a woman, you need to get X chromosomes from both parents.
So, 0.4% of the female population can blame the father as well.
From whom do we inherit baldness?
A large component that forms this problem also comes from the X chromosome, so you probably inherited this from your mother.
However, a study involving 52,000 people found that genes on other chromosomes can affect the condition, in addition to environmental factors such as age, stress and diet, so you probably shouldn’t blame your mother entirely. your.
Research has also found that the shape of the tip of the nose, the area above and below the lips, cheekbones and the inner corner of the eye are strongly influenced by genetics.
How do we divide our chromosomes?
Now, even if you receive half of your 46 chromosomes from your mother and the other half from your father, the results of a study involving genetically different mice found that for 60% of genes, the paternal copy was more active than the maternal copy.
This phenomenon is known as allelic imbalance.
The same study also noted that the brains of these mice look more like their father’s than their mother’s.
However, in humans we actually see the opposite.
Our brain is more like our mother’s, which is especially true for daughters. Interestingly, similar regions of the brain are actually associated with depressive disorders, suggesting that mood disorders can pass from mother to daughter.
From whom do we inherit DNA?
Biologists used to believe that all DNA comes from the nucleus, but now we know that mitochondria also play a role in some genes that encode proteins.
And this mitochondrial DNA is specifically inherited from your mother, because your father’s mitochondrial DNA degrades immediately after fertilization.
Given how important mitochondrial DNA is in the cell, there is a stronger maternal bond.
Mitochondrial DNA mutations have been associated with type 2 diabetes and Parkinson’s disease – which most likely came from your mother.
In the end, it may seem like a lot of traits actually come from your mother, or at least from the X chromosome, and that’s generally true, genetically.
The Y chromosome is very small and does not contain as many genes, and both women and men contain X chromosomes, which carry several genes.
But as we research more about ourselves at the genetic level, the division between that what did you receive from your mother vs. father it can become even more pronounced.
