Second meiotic division

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 second meiotic division, each of the two cells produced from first meiotic division 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: meiosis II

Compare: first meiotic division
