In brief: Father

Women have 2 x chromosomes, men have an x and a y.
The child will get one x from the mother, and either an x or a y from the father. If it is an x, you have a baby daughter. If a y, a son.

In brief: Ready 4 Complicated?

And the story of sex determination is actually far more complicated than many of us were taught in school.

In brief: Who Makes Gender?

Men determine the gender of the baby.
Boys have chromosomes x&y and girls have x&x. The y chromosome determines that the fetus will be a male and only men have a y chromosome. So, men determine the sex of the pregnancy. In cases of a single x chromosome, called turner syndrome, the child is female. For gender selection, we sort the sperm or test the embryos for the y chromosome.

In brief: Father

Males are made up of a total of 46 chromosomes (packages of dna), and two of those determine sex- an x chromosome and a y chromosome.
Women also have 46 chromosomes but have two x chromosomes. Sperm contain a half set of dna- 23 chromosomes including an x or a y, to add up with the egg's 23 chromosomes and an x to make a baby. Xx is a girl, xy is a boy.

In brief: The father

It is randomly determined.
In general, men will have an equal chance of producing y-sperm and x-sperm.
