WebApr 9, 2024 · Prometaphase II The nuclear envelopes are completely broken down, and the spindle is fully formed. Each sister chromatid forms an individual kinetochore that attaches to microtubules from opposite poles. Metaphase II The sister chromatids are maximally condensed and aligned at the equator of the cell. Anaphase II WebAnaphase II splits the sister chromatids which now separate (23 chromatids go to one pole and 23 chromatids go to other pole). When the chromatids are separated they are now called chromosomes so a …

WebThe X-shaped structures formed during separation are known as chiasmata. Diakinesis is marked by the termination of chiasmata and assembly of the meiotic spindle to separate the homologous chromosomes. The nucleolus disappears and the nuclear envelope breaks down. Meiosis 1 Metaphase 1 WebDuring meiosis II the sister chromatids separate and segregate. Note how meosis I and II are both divided into prophase, metaphase, anaphase, and telophase. After two rounds of cytokinesis, four cells will be produced, each with a single copy of each chromosome. open studios cornwall 2023
