Verified step by step guidance1
Understand that human gametes are reproductive cells, which include sperm in males and eggs in females.
Recognize that gametes are haploid cells, meaning they contain half the number of chromosomes compared to somatic (body) cells.
Recall that human somatic cells have 46 chromosomes, which are organized into 23 pairs.
Identify that one of these 23 pairs is the sex chromosome pair, which determines the sex of the individual.
Since gametes are haploid, they contain only one chromosome from each pair, including one sex chromosome, either an X or a Y.
