This happens during meiosis I, in the Anaphase I stage. Meiosis is a type of cell division in sexually reproducing organisms consisting of two rounds of cell division ( meiosis I and meiosis II) but only one round of DNA replication, result in cells with half the number of chromosomes sets as the original cell. In meiosis I homologs pair and segregate away from each other, the cell division in meiosis that separates homologous chromosomes, and after that the cells are haploid.
