As it turned out with the discovery of the Catalog of human population—since humanity as a biological type is divided into 293 subtypes, having a purely external similarity (“exterior”) a child does not inherit natural psychophysiological characteristics of his biological parents, except for when he is a representative of the same subtype as one of his parents (a mother or a father).
In the case of representatives of the biological type “human,” children are not antenna-like continuations of their biological parents, as it is the case in the world of animals and plants. In the world of Homo sapiens in most cases parents raise a representative or representatives who are not the same as their own subtype. This is the root cause of the well-known “problem of parents and children.” This is why children, even though they resemble their parents externally, in most cases do not get all characteristics and qualities of their characters, do not copy their way of life exactly as it happens in the animal world. And, sometimes they cardinally differ from their parents by nature.
As for similarity of characters, habits, attitudes, etc. observed in parents and children—this has nothing to do with their nature, and is only related to artificial “software.” We have fully researched this issue and it is described using popular language in the book called “Ahnenerbe”—Your Killer Is Under Your Skin by A. Davydov and O. Skorbatyuk.
