Could someone explain what the y and x chromosome are, what part they play in our biology and how they determine our sex? I hear this topic come up a lot and I have no idea what they are. Doesn’t an extra chromosome also mean a person might have down syndrome? Thanks guys.
(Not looking for a political debate btw, just straight biology, thank you)

The sex of a child is determined by two chromosomes. You get one from each parent. A female has two X and a male has 1X and 1Y. Female give X and if male give X the child is a female. If male gives Y the child will be male. As for the extra chromosome question downs is just one of a multitude of outcomes. The outcome is determined by which chromosome is the extra one. Hope this helps.
