Web5 apr. 2024 · The main difference between mitosis and meiosis is that mitosis is the equational division which means that the cell divides into two equal daughter cells. Meiosis is known as the reductional division. Meiosis normally occurs in the gamete cell. In meiosis cells, genetic material reduces to half (2n ⇢ n). WebDuring meiosis in humans, 1 diploid cell (with 46 chromosomes or 23 pairs) undergoes 2 cycles of cell division but only 1 round of DNA replication. The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell ...
