Webb30 apr. 2024 · In anaphase, there is a movement of chromatids towards the pole due to the shortening of the microtubules. During their poleward migration, the centromeres remain forward so that the chromosomes characteristically appear U, V or J- shaped. Interzonal fibers expand and support the movement of chromosomes towards the pole. WebbSolution. Following are the types of chromosomes and their shapes during anaphase:-.
