Why the chromosome number has reduced to half in daughter cells in process of meiosis?
Dear student, meiosis is a reduction division, which means the daughter cells receive half the number of chromosomes from the parent cells. This is because when fertilization occurs, the two gametic cells (1 from each parent) fuse together to form the zygote. During fertilization the original ploidy (diploid in case of humans ) is restored. If the daughter cells don't receive half the number of chromosomes , then on fertilization the zygote will become tetraploid. Thus it is important that the number of chromosomes received in each daughter cell if half that of the parent in case of meiosis to restore the normal ploidy in the progeny. Regards.
