Which chromosome pair determines female sex in humans?

Explanation:
Sex in humans is determined by the sex chromosomes. The Y chromosome, carrying the SRY gene, drives male development when present; without a Y, the default path in humans is to develop as female if there are two X chromosomes. Therefore, the chromosome pair that determines female sex is two X chromosomes. Rare variations exist, like Turner syndrome (one X) where individuals are phenotypically female, or the nonviable YY scenario, but the standard determinant for female sex is XX.
