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 WebJul 7, 2024 · During anaphase, the following key changes occur: The paired centromeres in each distinct chromosome begin to move apart. Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes .
