In this phase two chromosomes of each bivalent separate and move towards the opposite poles due to spindle action. In anaphase II of meiosis II, the sister chromatids are pulled apart. This separation of homologous chromosomes and sister chromatids in anaphase I and II respectively is called disjunction.

Answer:

In this phase two chromosomes of each bivalent separate and move towards the opposite poles due to spindle action. In anaphase II of meiosis II, the sister chromatids are pulled apart. This separation of homologous chromosomes and sister chromatids in anaphase I and II respectively is called disjunction.

Explanation:

metaphase

It has been proposed but never proven that cohesion between sister chromatids distal to chiasmata is responsible for holding homologous chromosomes together while spindles attempt to pull them toward opposite poles during metaphase of meiosis I.
