  • The number of chromosomes decreases during meiotic division, and it increases upon fertilization. Thus, meiosis and fertilization seem to be biologically independent and different events. However, in many animals, fertilization occurs during meiotic division of oocytes. The timing of fertilization is definitely restricted; fertilization does not occur until meiosis proceeds to an appropriate stage and meiosis reinitiation is induced by fertilization. I am interested in the fact that meiosis and fertilization proceed interactively, and would like to find molecular mechanisms of the interaction using starfish and mouse oocytes.
