We are actually a genetic cocktail made from the cells of many of our ancestors.
What determines whether a child will look like a mother or a father, or even their parents, brothers, sisters?
Everything, absolutely everything – appearance, character, way of making decisions … It all depends on the genes we inherited. The baby receives 50 percent of the genetic material from the mother and the other half from the father. However, both the mother and father of the baby carry 50 percent of their father’s and mother’s genes, etc. The result is a constant “crossing” of genes. That can make a kind of genetic cocktail made up of the cells of many of our ancestors.
Why do some children look like their mother and some like their father?
By their participation, genes are divided into dominant and recessive in the structure of the newly created organism. Dominant genes include genes for vision and hearing, right-handedness, average growth, glucose absorption, dark hair, and thousands of others.
On the other hand, genes for blindness and deafness, left-handedness, drastically low or high growth, predisposition to diabetes, blond hair, etc. are considered recessive. People like this are in a large minority. All these genes, recessive and dominant, will define the characteristics of the next generation.
Gene compatibility and child appearance
Each branch of the human gene has it’s own dominant and recessive genes. If a father’s family, for example, has red hair genes, the child’s genes may be dominant. If the DNA of a mother with blonde hair and impeccable complexion contains the same recessive gene, most of the couple’s children will be redheaded. Blondes with a clear complexion will be in a large minority if they are born like that.
Yet even if the mother doesn’t have such a recessive gene, one of her four children will be a copy of the redheaded father. That’s where another law of genetics comes into play – the dominant gene of both parents comes in a 1: 2: 1 ratio, under any circumstances.

It looks mostly like this: one child will be blue, the other redhead, and the next two will have mixed features of both parents. Even if the mother decides to have an abortion, a gene cocktail has already been formed and is ready to await the next organism.
There are many dominant and recessive genes in every organism, so no one is able to count all the possible combinations. In any case, only the strongest genes, whether they come from father, mother or grandparents, will be seen in the child’s appearance.
