During mitosis, the chromosomes of parent cells will be duplicated to get equally distributed
among two daughter cells. Whereas meiosis is a reduction division, where one diploid cell will
divide to generate haploid cells. DNA replication takes place during mitosis as well as during
meiosis interphase I. Meiosis produces four cells with only one set of chromosomes (n), so it is
involved in the production of sperms and eggs and these during fertilization fuse to produce a
fertilized egg (2n). Tetrads are formed with the pairing up of homologous chromosomes during
the process of Crossing-over, and it occurs only during meiosis. It is the mitosis, or normal cell
division which helps the human fetus to develop through deposition of extracellular materials as
the embryo grows.
