Answer:
It is important that meiosis produces a haploid cell because it prevents the number of chromosomes from doubling each generation. If mitosis were used to produce gametes the subsequent generations would be diploid so in the next generations the normal amount of chromosomes would double meaning each subsequent generation would double the number chromosomes again and again.
Explanation:
Meiosis
- the process by which the number of chromosomes is halved during the formation of gametes.
- In human cells, for example, 46 chromosomes are arranged in 23 pairs. Therefore, human cells are diploid i.e. they have two sets of 23 chromosomes per set. During generative reproduction, the sex cells of the parent organism unite with one another and form a fertilized egg. In this situation, each sex cell is gamete. Gametes from haploid human cells, from Greek haplos, which means "single." This term implies that each gamete contains a set of 23 chromosomes in humans. When human gametes unite with each other, the original diploid condition of 46 chromosomes is rebuilt. Meaning cells containing a diploid number of chromosomes are converted into four cells, each of which has a number of haploid chromosomes. In human cells, for example, reproductive cells containing 46 chromosomes produce four cells, each with 23 chromosomes.
Mitosis
- the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus. Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
-In each cycle of cell division, two daughter cells are formed from the parent cell. The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.
