What are the sex chromosomes of a human male?

Answer and explanation

Correct answer: XY

A typical human male has one X chromosome and one Y chromosome, represented as XY. The X chromosome is present in both sexes, whereas the Y chromosome is usually associated with male development. XX is the usual female combination. YY is not a normal viable human chromosome complement, and OO is not a recognised human sex-chromosome combination. Therefore option B is correct.
