WebMar 4, 2024 · In human diploid cells, there are 23 pairs of homologous chromosomes. After meiosis I, two cells are present, each with 23 different chromosomes that are still in duplicate as sister... WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair.
