I will explain, but I don't know why you put this in cat behavior.
The X chromosome and Y chromosome control gender. If an embryo's two chromosomes are XX, it will be a girl. If the chromosomes are XY, it will be male. A pair of chromosomes have to have at least one X chromosome in it, but can also have a Y chromosome.

∙ 12y agoA spermazota (sperm cell) controls the gender of a fetus and therefore a baby because a woman's egg will always have an X chromosome while a man's sperm will have either an X or Y chromosome; the sperm's Y chromosome makes a male child while the sperm's Y chromosome makes a female child.

∙ 12y agoThe sperm from the father determines the sex of the new baby. Ova (or egg cells) have the X chromosome, sperm cells have either an X or a Y chromosome. The XY combination produces a boy baby. The XX combination produces a girl baby.
