Sex Determination
The egg gamete mother cell is said to be homogametic, because all its cell possess the XX sex chromosomes. sperm gametes are deemed heterogametic because around half of them contain the X chromosome and others possess the Y chromosome to compliment the first X chromosome.
In light of this, there are two possibilities that can occur during fertilisation between male and female gametes, XX and XY. Since sperm are the variable factor (i.e. which sperm fertilises the egg) they are responsible for determining sex.

And to all my beautiful girlfriends, in future, when you get pressuring comments from your in-laws, please educate them. For self protection sake: My recommended statement would be : "Blame your precious son la. Who ask him to be so useless!?!" FULL STOP.
