Q. In which meiotic division does the separation of the homologous take place and what are the ploidies of the generated cells after the end of that process?
The separation of the homologous chromosomes occurs in the first division of meiosis I or meiosis. After the end of this cell division two haploid cells are made, each having different chromosomes with no set of homologous. Note that in the cells generated after meiosis I each chromosome is still duplicated from the time when the homologous chromosomes and not the identical chromatids were separated.
