What gene determines if a child will be a boy or girl?

The sex of a child is determined by the sex chromosome present in the father's sperm cell. If he donates an X, the child will be a girl, if he donates a Y, the child will be a boy. The historical or ancestral lineage doesn't have anything to do with the child's sex.

Whose sex chromosomes determine a child's sex?

The sex chromosomes that determine a child's sex are inherited from the biological parents. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. The combination of these chromosomes determines the child's sex, with XX resulting in a female and XY resulting in a male.


What gamete determines the sex of a child?

The sperm from the father can supply either an X-bearing or a Y-bearing chromosome. The egg from the mother can only supply an X-bearing chromosome. An XY combination produces a boy baby. An XX combination produces a girl baby. It might seem that the father therefore determines the sex of the baby, but some recent evidence suggests that the mother can select either an X-bearing or a Y-bearing sperm. See the Wikipedia article on "Maternal influence on sex determination."

Which gamete determines the gender of the young?

In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.
