WebApr 11, 2024 · We can think of meiosis as a way cells very carefully count and divide their chromosomes so that each gamete, each egg or sperm, has exactly 23 chromosomes. Then when an egg with its 23 chromosomes is fertilized by a sperm with its 23 chromosomes, the resulting fertilized egg has exactly 46 chromosomes. WebSolved by verified expert. 1-Mitosis maintains the chromosome number because it divides one cell's genetic material into two daughter cells with the same number of chromosomes as its original parent cell. Mitosis plays an important role in body processes like tissue repair and growth. 2-Microtubules are essential in nuclear division, or mitosis.
