What sex chromosomes are found in human egg cells?

Explanation:
Eggs are haploid gametes that carry only one sex chromosome. In humans, females have two X chromosomes, and the meiosis that forms eggs always yields eggs with a single X. A sperm from the father can contribute either an X or a Y, which then determines the offspring’s sex. So the sex chromosome in human egg cells is X. The other possibilities would require the egg to carry a Y, two sex chromosomes, or a chromosome not present as a human sex chromosome, which doesn’t happen in normal development.
