When a couple becomes pregnant (well, the one who stays is the woman, of course), it is usual to think about how the baby will be, who will it look like, how will your eyes, your mouth, your nose, etc.
The truth is that answering this question is quite difficult, since there are many possible combinations of DNA that can occur. To put figures, it is said that a couple can have 70 billion different babies, almost nothing.
However, there are couples in which the genes of one of the two tend to be more dominant and therefore children are more like him (or her). A clear example may be the Bourbon family, which with all my respects, are all the same or mine, that I know are my children because I trust my wife, if not ...
I will talk a little more about the subject to know some curiosities about the functioning of the genetic framework.
Each person receives genes from their mother and father in a 50/50 ratio and therefore receives genetic inheritance from their grandparents in 25/25/25/25 proportion.
Within all that amount of genes, there is one part that does manifest and another that is inherited but not visible and that can be transmitted to later generations.
In other words. Your son may resemble your wife damnly, but he can transmit to his children part of that 50% that he carries with you (I'm afraid only 25%, as I said) and that these genes manifest themselves in your grandchildren, looking more like you your grandchildren than your own children (it's the only hope I have left).
It is for this reason that many times two parents with brown eyes have a child with blue eyes like grandfather (it is good in these cases that the father is informed of this possibility, just in case you have doubts ...).
Many people say that "it is logical, because genes skip a generation." This is not a phenomenon that really happens, but it is about genes that in a child have not manifested and by chance they do in the grandson.
Surely more than once you will have wondered why with the amount of people in the world, and having all such common characteristics as two eyes, a mouth, a nose and two eyebrows we are so different (the only ones that are equal to another being is the univiteline twins).
The answer is that the process of genetic selection that occurs when an egg and a sperm join together is totally unpredictable, because of the amount of genes that come into play (about 30,000 from the father and many others from the mother). They are so many, that Even when we had 10 children, everyone would be different.
In short, it is virtually impossible to answer the question: Who will my baby look like? In fact, it doesn't make much sense to question it before birth because once you have your baby in your arms you will realize that not even seeing it, people agree.
The mother's family will see hundreds of similarities to the mother, her relatives and if you hurry me up to the uncle who does not even have a relationship of consanguinity.
The family of the father, similarly, "nailed the child to the father" and with the gestures of grandfather Manuel, may he rest in peace.
To all future dads and all future moms: I wish you luck in this regard (and patience, which you will need).
