In humans, which chromosome constitution corresponds to a male?

Explanation:
Sex determination in humans is decided by the sex chromosomes. A typical male has one X and one Y chromosome, while a typical female has two X chromosomes. The Y chromosome carries the SRY gene that triggers the development of male characteristics. Without a Y, or with two Xs, development tends toward female. A chromosome pattern of X0 is Turner syndrome and is usually female; XX is female; YY is not viable in humans. Therefore, the pattern that corresponds to a male is XY.
