There are thousands of stories when children in the same place as their parents had a noticeable mole. Family resemblance type. This is actually an accidental similarity.
Moles are growths from the pigment cells of the skin. They appear more often in people with pale skin.
In fact, these are like tumors, but on average, malignant tumors rarely grow from moles. Therefore, neither people sprinkled with moles, nor doctors bother too much with these moles.
Moles usually appear after exposure to the sun. And the longer a person sprays himself with a tan, the more moles he will have.
Moles are like small independent creatures: they are born, grow, grow old, get sick and die. Therefore, children and the elderly have fewer moles than people of reproductive age.
It is said that the average lifespan of a mole is about 50 years. If she is lucky, she will die before you.
If a person has more than 50 noticeable moles on the body, then something is clearly wrong with this case, and he has a higher risk of developing melanoma.
During our evolution, our body has realized that it will not be able to cope with moles completely and waved its hand at them. He simply controls their birth rate and growth with the help of genes specially sharpened for this business. If a gene malfunctions, then moles either multiply, or grow uncontrollably, or malignant tumors grow out of them.
It turns out that a predisposition to the appearance of a large number of moles, or to the growth of moles to a large size, or to the development of a malignant tumor can be transmitted to us by inheritance. But the very location of the birthmark is not inherited. Well, that is, there may be a tendency to the appearance of moles on the back, but the mother's charming fly on the left cheek is not transmitted to the baby. No. This process is unpredictable. It's just a mutation in the skin.
or like this
In humans, a tendency to the appearance of large moles is inherited. Sooner or later, a family will gather in which these large moles will accidentally sit in approximately the same place with grandmother, dad and daughter. Everyone around me likes this. But those around them simply did not see many similar families, where there were also large moles, but on different and not matching parts of the body. People like to find patterns and come up with all kinds of things.
Cave people
They say that this tendency to invent all sorts of nonsense developed in our ancestors evolutionary. Well, that is, if we got a big brain, then natural selection uses this brain to make us survive.
In primitive times, people still could not use their brains to build a steam locomotive or even a bicycle, but they already knew how to fantasize.
If such a primitive man went to a large and terrible cave, then with his big brain he imagined a babayka who was waiting for him inside. Thus, natural selection selected those who did not rashly enter the cave to the short-faced bear. Primitive dreamers often survived and passed on to their descendants a tendency to find patterns where they did not exist. So in matters of health, people often invent something for themselves.
Briefly speaking
The tendency to the appearance of moles can be inherited, but their exact location cannot be transmitted. Moles appear unpredictably from random mutations in skin cells.
