Solution

The correct option is B Anaphase II
In anaphase-II, sister chromatids aligned on the equatorial plate get separated and move towards the opposite poles.

Though separation of homologous chromosomes occurs in anaphase-I, however, the final destiny of the genetic composition of the gametes is decided in anaphase-II.

This is because the genetic composition of sister chromatids can be different due to crossing over.

Final answer: b. Anaphase-II.
