What processes are responsible for the generation of genetic variation during meiosis, and at what point in meiosis does each occur? Random alignment and separation of homologs that takes place during metaphase I and anaphase I, respectively. Independent assortment of homologous that takes place during anaphase II. Crossing over of non-sister chromatids that take place during prophase I. Replication of DNA during the S phase.
