In humans, females typically have two X chromosomes (XX) as their sex chromosomes. This means that while males have one X and one Y chromosome (XY), females are equipped with a pair of Xs, which not only dictates their sex but also plays a crucial role in other genetic traits and disorders. A human egg cell contains half the number of chromosomes found in a typical somatic cell, which means it holds 23 chromosomes. This reduction is essential for sexual reproduction, as it ensures that when the egg merges with a sperm cell (also containing 23 chromosomes), the resulting zygote has the standard 46 chromosomes, maintaining the species' genetic integrity!
