in what depends upon the child to be a girl or a boy?
i thought in the chromosones of the father but i read an article on the internet that it depends on the way the mother eats before the pregnancy.

The sex of a baby is determined soley on the chromosomes that the baby recieves. The mother supplies the egg and the father supplies the sperm. All normal eggs have one X chromosome. Fifty percent of normal sperm have one X chromosome and the other fifty percent of normal sperm have one Y chromosome.
A normal baby will end XX if the sperm that fertilizes the egg carries an X. A normal baby will end up with XY if the sperm that fertilizes the egg carries a Y.
XY = boy
XX = girl
The way the mother eats has no bearing on the determination of the sex, but it can affect chances of conceiving and the development of the baby.
