Meiosis, or reductional division, is a process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetical material occurs the four daughtercells
have received each only one set of chromosomes (they are haploid, in
contrast to the mother cell which contained homolog chromosomes and was
diploid)
have each a distinct genetical composition, also different from that of the parental cell.
Meiosis is divided into twofases: meiosis I and meiosis II.
