How many mature egg cells result from meiosis
WebCells reproduce through mitosis to make exact copies of the original cell. This is done for growth and repair. Sexually-reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes. Web31 dec. 2024 · Meiosis is a process of cell division in eukaryotes characterized by: two consecutive divisions: meiosis I and meiosis II no DNA synthesis (no S phase) between the two divisions the result: 4 cells with half the number of chromosomes of the starting cell, e.g., 2n → n Fusion of two such cells produces a 2n zygote.
