Sex, as in gender, is determined by the sex organs possessed by an individual. Genetic errors and mutations can make it difficult to determine by just this, but more sophisticated methods exist.
The presence or absence of a y chromosome determines the sex of an individual. If a child had received a y chromosome from the father it is a boy, if it has received an x chromosome from its father is a girl. A child always receives an x chromosome from its mother, thus it is always the fathers contribution that determines the sex.
X and Y chromosomes. The male sperm are all either X or Y. The female egg is completely X.
If the sperm enters the egg and you have an XX baby it's a girl, and if you have an XY baby it's a boy.
The male chromosome will be the determining factor of the sex of an individual, specifically the Y chromosome.
