Because the child's sex is determined by a pair of chromosomes, called X and Y. Each parent contributes one of the chromosomes. Females have nothing but X's, so they can contribute only an X. Males have an X and a Y. The male can contribute either one; it's a toss-up. If the male contributes an X, the result is XX, a girl. If the male contributes a Y, the result is XY, a boy.

Why does the father ultimately determine thesex if the baby?
The sex of a child is determined by the father because the genes that determine sex come from the male sperm.

The sex of a child is determined by the sex chromosome of the sperm cell (which comes from the father). If it is a Y, the child will be a boy, if it is an X, the child will be a girl.
The sex of a child is determined by?
In humans the sex of the offspring is determined by which sperm is able to fertilize the ovum. If a sperm containing the X chromosome fertilizes the ovum, a female offspring results. If a sperm containing the Y chromosome fertilizes the ovum, a male offspring results
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.
How is a bady is made?

A child will be a girl if she receives what chromosomes from father and what chromosomes from mother?
A child's sex is actually determined entirely by his or her father. All eggs in a woman's body contain and X chromosome, whereas sperm cells contain either X or Y. The female sex chromosomes are XX and the male sex chromosomes are XY. Thus, if the sperm that fertilizes the egg contains an X chromosome, the child will be a girl. If the sperm contains a Y chromosome, the child will be a boy.

The sex of a child is determined by the father because the genes that determine sex come from the male sperm.
If parents have a baby girl and want their second baby to be a boy what do they do?
There is no reliable "natural" method for ensuring the sex of a baby. As sperm are responsible for the baby's sex, it would be necessary either to ensure that the male produces sperm carrying the appropriate chromosomes for the desired sex. There is no way of doing this. Optionally, it is possible to increase the concentration within semen of sperm carrying the coding for one sex or the other, as the two different kinds of sperm are of different weights, and semen can be processed in a centrifuge to separate lighter from heavier sperm. This does not guarantee results, but increase the chance of fertilisation by a sperm of the desired sex. Of course, this process requires use of a form of IVF. This process is difficult and generally only used when serious adverse results are expected if a child is of a particular sex. Filtering techniques are of no use, of course, for men who only produce viable sperm for one sex but not the other. The simplest solutions are adoption or being content with whatever you get.

Does the egg determine the sex of a child?
No, the egg is from the mother and can only carry the X chromosome (since the mother is XX). The sperm will be either X or Y (since the father is XY), and will determine the sex of the child.
