Meiosis II

Definition

The second of the two consecutive divisions of the nucleus of eukaryotic cell during meiosis, and composed of the following stages: prophase II, metaphase II, anaphase II, and telophase II.


Supplement

During meiosis II, each of the two cells produced from meiosis I divides further into two cells, each containing one of every decoupled chromosome’s sister strands (chromatids), thus, producing four genetically different, haploid cells.


Also called: second meiotic division

Compare: meiosis I

Re: Multicellular prokaryote

... differentiation, and importantly: endocystosis which allowed for the 'taking in' of other organisms. Sexual reproduction (especially meiosis) yielded new organisms which were both distinct but also compatible, arising from a single new cell. Essentially, eukaryotic organisms can be ...
