Meiosis occurs in which of the following cells?

Meiosis is a specialized type of cell division that occurs in germ cells, which are the reproductive cells involved in sexual reproduction. This process results in the formation of gametes—sperm and eggs in humans and many other organisms. During meiosis, a single germ cell undergoes two rounds of division, ultimately producing four genetically diverse haploid cells, each containing half the original number of chromosomes. This reduction is critical for maintaining the species' chromosome count when fertilization occurs, allowing for genetic variation essential for evolution and adaptation.

In contrast, skin cells, blood cells, and brain cells do not undergo meiosis. Instead, these cells replicate through mitosis, a process that results in two identical daughter cells for growth and tissue repair. This distinction between the types of cell division is crucial for understanding cellular function and the reproductive process in living organisms.
