Which genotype represents a typical human female?

Explanation:
In humans, sex is determined by the sex chromosomes. A typical human female has two X chromosomes, giving the genotype XX. This pair of X chromosomes directs female development. In contrast, XY is typical for males, X0 (only one X) leads to Turner syndrome and is not a normal female genotype, and YY isn’t viable in humans. Therefore, XX is the typical female genotype.
