meiosis (maɪˈəʊsɪs) n,pl-ses(-ˌsiːz) 1.(Biology) a type of cell division in which a nucleus divides into four daughter nuclei, each containing half the chromosome number of the parent nucleus: occurs in all sexually reproducing organisms in which haploid gametes or spor...
One apparently normal spore, which later germinated, is assumed to have resulted from the formation of a restitution nucleus at the end of meiosis I.The total lack of pairing among the 29 chromosomes of this plant is evidence that this number represents the basic haploid complement of the ...

Meiosis is a special form of cell division that maintains the correct number of chromosomes in gamete cells, proceeding continuously through several phases. Meiosis I is the phase in which two haploid cells are produced from a single diploid cell. What happens during the pachynema stage of ...
