Genetically speaking, the gender of a baby is determined by the presence of the 'Y' chromosome (or the absence of it).

If a Punnett square were to be drawn and a mono-hybrid cross carried out, you can see that the only chromosome the female (XX) can pass on is the X chromosome. The male (XY) can pass on either his 'X' or his 'Y'.

If the male passes on his X chromosome, the two chromosomes fuse to form XX, therefore becoming female. But if the male passes on his Y chromosome, XY is formed which is a male. Hence, the male always determines the gender of an offspring.

The male chromosome that determines the gender of a baby is the Y chromosome. When a sperm carrying a Y chromosome fertilizes an egg, the baby will be male. If the sperm carries an X chromosome, the baby will be female.

That would be the Y chromosome. Females are XX, males are XY (with some very rare exceptions. Also, the male's X or Y chromosome will determine the baby's sex.

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.

Does the sperm determine the gender of a baby?

No. The male determines the sex. A female has 2 X chromosomes, while a man has an X and a Y. A woman can only give an X, but a man can give an X or a Y, thus making the sperm cells the determining factor.
