Question

which pair of human chromosomes will determine the persons sex?

Explanation:

In humans, there are 23 pairs of chromosomes. 22 pairs are autosomes (non - sex chromosomes) and 1 pair is the sex chromosomes. The sex chromosomes are named X and Y. Females typically have two X chromosomes (XX), and males typically have one X and one Y chromosome (XY). The combination of these sex chromosomes (the 23rd pair) determines the biological sex of an individual.

Answer:

The 23rd pair of chromosomes (the sex chromosomes: X and Y) determines a person's sex.
