Nondisjunction will occur . Yep
Kleinfelter's syndrome.
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
An embryo, male or female, usually has two sex chromosomes, one from mom, one from dad. In a male's case, they would be XY. Rarely, nondisjunction occurs, and a child winds up XXX, XXY, XYY, or X. XXX and X become female, and XXY and XYY become male. So, it is theoretically possible for a male embryo to have three sex chromosomes.
No actually it is a sex-linked trait.
It is estimated that about in in 500 men have Klinefelter's syndrome.

Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.

XXY. Klinefelter is caused when the X chromosomes of the mother fail to split, or an XY sperm reaches an X egg, resulting in a mostly male child.
1 pair of sex chromosomes Female pair is XX Male pair is XY
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
Well you don't "get" it like you get a common cold. You are born with it due to a genetic mutation on your sex chromosomes causing the XXY gene instead of XY, like in a non-Klinefelter, male.
It is the father's contribution that determines the sex of the offspring. Of the XX and XY pairs that determine sex, the mother always contributes an X. If the father contributes an X as well, the offspring is female. If the father contributes a Y, the offspring is male.
A diploid human cell has two sex chromosomes. However, the number of sex chromosomes can vary between individuals. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY).
