The father determines the sex of the child. Whether the child is male or female depends on the combination of chromosomes in the sperm that fertilizes the egg. A man has both 'X' & 'Y' Chromosomes. A woman only has 'X'. One X will come from the mother & either another X will be released by the father or a Y is. If an 'XY' fertilizes said egg; the child will be a boy, if an 'XX' sperm fertilizes the egg then the child will be a girl.
The sperm from the father can supply either an X or a Y chromosome. The egg from the mother can only supply an X 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."
The sperm give either an X or a Y chromosome to the egg, which is an X. Boys are XY and girls are XX.
The male because he has an x and a y sex chromosome, whereas the female has two x sex chromosomes.
The father. The mother contributes a X chromosome and the father contributes a X (XX for girl) or a Y (XY for boy).
