What is required for the separation of homologous chromosomes at anaphase I?

The dissolution of the chiasmata is required for the separation of homologous chromosomes at anaphase I. Chiasmata are the points of crossing-over between homologous chromosomes, and they hold the chromosomes together until anaphase I. At anaphase I, the chiasmata dissolve, allowing the homologous chromosomes to separate and move to opposite poles of the cell.
