Meiosis (/ m aɪ ˈ oʊ s ɪ s / (); from Greek μείωσις, meiosis, which means lessening) is a special type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

Occasionally, there are hermaphrodites in place of one or both sexes. There are also some species that are only one sex due to parthenogenesis, the act of a female reproducing without.

Laboratory 8: Mitosis and Meiosis 5 sex chromosomes (the pair of chromosomes responsible for determining the gender of an individual). Now let us have a look into the number of chromosomes and DNA molecules at different stages of cell cycle. Let the chromosome number of a cell at G1 phase of interphase is 8. First think carefully in what all stages changes in number of DNA molecules and chromosomes takes place.
