X & Y chromosome

We all know about the basic XX and Xy, but I'm just wondering...

1) Can a physiologically normal female human have Y chromosome in her body?
2) Does a physiological normal female has Y chromosome in her autosome?
3) (T/F) Normal female will always produce gamete with X, never with Y?
4) Can a physiologically normal human male has any kind of cell in his body that has XX homologs?
5) (T/F) A normal physiological human male always make X and Y gamete?
6) (T/F) A son always inherit his Y chromosome from his dad?

I agree with Electrons on all of them. On 4 and 5, nondisjunction can change the answer, but only due to mutations.

I think even with nondisjunction 4&5 is still True, True respectively. Nondisjunciton can't make Y chrom..even mutation...it has to be major drastic mutation to turn X into Y. Right?

Actually, I was thinking of something else, but I was wrong. I think they are always true. I wasn't thinking that X would turn into Y but instead they wouldn't split properly or somehow the Xs would replicate twice or the Ys would replicate twice. anyway....
