CHAPTER 22: THE REPRODUCTIVE SYSTEMS
F. The (Specific) Stages of Meiosis:
4.Meiosis II:Fig 22.8, page 887.
b.4 stages similar to those of mitosis, with
centromere splitting (between duplicated chromosomes) and
sister chromatids migrating to opposite poles during Anaphase II.
4.Telophase II and cytokinesis.
c.Result is 4 gametes with 23 chromosomes.
*During spermatogenesis, 4 sperm result.
*During oogenesis, only 1 ovum results due to unequal cytokinesis (i.e. polar bodies result; discussed later).
G.Comparison of Mitosis and Meiosis: (Keyed on page 30 of this outline)
Number of Divisions
Number of daughter cells & genetic composition
