Is it true that inheritance from one’s father is real?

Patriarchal inheritance refers to the comparison of the characteristics of the predecessor among the parents, and patriarchal inheritance mainly refers to the characteristics and personality of the predecessor. Generally speaking, some women separate from their former partners and then remarry, and their subsequent children may still have some characteristics, looks and similarities with their former husbands. Generally speaking, patriarchal inheritance rarely exists. Since the fertilized egg is divided into different cells for development, patriarchal inheritance generally does not exist.

Is paternal inheritance true?

What is paternal inheritance?

Pre-paternal inheritance refers to the theory that offspring can inherit the characteristics of one of the parents' previous partners, which varies from person to person or species to species. The mother's body is invaded by the paternal medium and the genome or exogenome of the germ cells is tampered with, so the offspring born later inherit the characteristics of the paternal medium. Some mammals have paternal inheritance.

Patriarchal inheritance is a theory of inheritance that has been much questioned. The theory holds that a parent inherits traits from his or her mother's previous spouse; therefore, the children of widows and remarried women are likely to carry the traits of their previous husband.

Is paternal inheritance true?

"Paternal inheritance" has long been denied by modern genetics, and scientists have not yet found conclusive evidence of its existence. Some so-called "paternal inheritance" phenomena are actually manifestations of dominant and recessive genes.

"Inheritance from the father" is a fallacy. The sperm and egg of mammals each have a set of chromosomes, which combine to form one cell - the fertilized egg, half of whose genetic material comes from the father and the other half from the mother. The process of conception is the continuous division of the fertilized egg, from 1 cell to 2 cells, and then to 4 cells. These cells then differentiate in various directions to form eyes, ears, mouth, nose, limbs, etc.

If the child has the genetic characteristics of the woman's previous male partner, then the genetic material of the original cell - the fertilized egg - must have changed. Since the sperm comes from a man, the only thing that has changed is the woman's reproductive cell - the egg. The foreign genetic material can only be integrated into it before it can be passed on to the next generation. After a man ejaculates in a woman's vagina, most of the sperm are unable to combine with the egg and quickly dissolve. Their proteins, carbohydrates, DNA, etc. will be broken down and metabolized and eventually excreted from the body. They cannot stay in the human body for a long time, and cannot change the woman's genes. This is because genetic modification is difficult to occur naturally and requires complex technology to be achieved in the laboratory. Obviously, sperm does not have the ability to invade female cells. Its genetic material DNA is broken down into basic units - nucleotides and then absorbed and utilized by the human body, rather than the entire DNA sequence being absorbed. Experts made an analogy, saying: "We will not become cattle or sheep after eating beef or mutton, because their genes will not be integrated into human cells."

To take a step back, even if sperm has the ability to be genetically modified, it cannot achieve "inheritance from the father". Deng Minduan explained that a woman's reproductive cells are formed when she herself is still a fetus, and the total number is as high as millions. It is not until puberty that the ovarian function starts and menstruation occurs, that the follicles in the ovaries gradually develop, and during ovulation, a mature egg combines with sperm to become a fertilized egg. If the semen of a former male partner wanted to change the genetic material of the egg, it would have to penetrate millions of cells and change all of their genetic material, which is impossible.

Some people feel that their children are similar to their wife's old lover, which arouses suspicion and jealousy. After all, the children and the ex-boyfriend belong to the same race and are even from the same place, so the similarities are easy to explain.
