The separation of homologous chromosomes occurs in
The correct option is A Anaphase I
Prophase I includes the pairing of homologous chromosomes and cross over. Anaphase I and anaphase II include separation and movement of homologous chromosomes and sister chromatids to opposite poles respectively. Prophase II is marked by condensation of chromatin material. Homologous chromosomes align themselves at cell's equator during metaphase I. Thus, the correct answer is option A.
