This is NOT true. Meiosis is a type of cell division that results in four daughter cells that are the same but are different from the parent cell because tgeyhave HALF the number of chromosomes.

@Rachel A I do not think so. Since crossing over of homologous chromosome and independent assort occurs, variations of gametes will be produced. Independent assortment means one chromosome from each pair can combine with either chromosome of the other pairs. Let’s say the number of chromosome of haploid cell is (n), then diploid cells is (2n). 23 chromosomes are from a male and 23 are from a female. That is 46 in total and 23 pairs of homologous chromosome ( or 23 pairs of bivalent) Since meiosis produces gametes that are haploid, that is (n), for human, that is 46/2= 23 chromosomes. To obtain 23 chromosomes, random assortment basically RANDOMLY chooses 1 out of 2 chromosomes (either from male or female) for 23 types of chromosomes. Hence, the number of the daughter cells is actually 2^23, that is 8388608 possible daughter cells to be produced. Therefore, daughter cells are not identical to each other, nor to the parent cell. Please correct me if I made any mistakes.

So, to clarify, the daughter cells produced in meiosis are identical to each other, but not the parent cell?03/28/22
