Webb10 apr. 2024 · Meiosis is the process of producing gametes—sex cells, or sperm and eggs in the human body. In a human being, the haploid cells made in meiosis are sperm and eggs. At the point when a sperm and an egg participate in fertilization, the two haploid arrangements of chromosomes create a complete diploid set: another genome.
