I can't answer the last two questions definitively, but XX indicates female, XY indicates male. One X chromosome is consistently dropped by the mother, but it's up to whatever sperm from the father fertilizes the egg to determine the second X or the Y. So when Henry VIII was killing his wives for failing to produce a male heir... in reality, it was his li'l guy's fault for not spitting out the right genetic code.
