The sex of children is determined by the presence of either an X or Y chromosome in the father’s sperm, which determines whether the offspring will be male (XY) or female (XX).

The sex of children is determined by the presence of either an X or Y chromosome in the father’s sperm, which determines whether the offspring will be male (XY) or female (XX).
The sex of children is determined by the genetic contribution of the father’s chromosomes, specifically the presence of either an X or Y chromosome within his sperm cells. During fertilization, if an egg is fertilized by a sperm carrying an X chromosome, the resulting embryo will develop into a female (XX). Conversely, if the sperm carries a Y chromosome, the embryo will develop into a male (XY).
This process occurs during conception and is solely dependent on the genetic makeup of the father’s sperm. While the mother contributes an X chromosome to all of her eggs, it is the type of sperm (X or Y) that fertilizes the egg that ultimately determines the sex of the offspring. Therefore, the sex of children is primarily influenced by the father’s chromosomes, specifically the presence or absence of the Y chromosome in his sperm.
