It`s the man who decides, because a female has 2 x chromosomes and a male has 1 x and 1 y, so if the baby is a boy, it had to get the decision from the male sperm, the girl gets a x gene from each person. Therefore the male gave the gene to create a girl.

the male [provides an x or Y chromosome in the sperm. as a result he his genes " decide" whether a baby is male of female.

It's the father's genes. X chromosome gives you girl and Y chromosome gives you boy.

not genes ... but it the fluid that is called semen that takes care of it ... semen is collection of sperms ... its just that one lucky sperm that reaches the goal(the egg) and then the decision is made !
Its all about Xs and Ys chromosomes ... thats the reason why I always told you to study Biology ... but you never listened !

well, men have XY chromosomes when they let out their semen. women's eggs are XX. so if the Y chromosomes overpower the double X, you get a boy. If the chromosomes turn out to be XX, then you get a girl.

Sperm come in X and Y. Y is male, X is female. The egg is always X..
There are times that there is XXY or XYY, but it is rare.
Anyways, it is the male sperm that choose.

It's what the father contributes that determines the sex of a child.
