What are the sex chromosomes of a human female?

Answer and explanation

Correct answer: XX

In the standard human chromosome pattern, females possess two X sex chromosomes, written as XX. During reproduction, a female’s egg normally carries one X chromosome. An XY combination is typically associated with a male, YY cannot normally form a viable human individual because an X chromosome is required, and XO represents a different chromosomal condition rather than the usual female complement. Hence option A is correct.
