Web8 aug. 2024 · At the end of meiosis I, there will be 2 haploid daughter cells, one with n+1 and the other with n-1. Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II. WebThe four aspects of Meiosis 2 are Prophase 2, Metaphase 2, Anaphase 2 and Telophase 2.
