Answer Key: Mitosis only, Meiosis Only, Both Mitosis and Meiosis, Neither In , independent assortment of chromosomes occurs. In , daughter cells are identical to the mother cell. In , homologous chromosomes consisting of sister chromatids line up separately along the metaphase plate. In , the synaptonemal complex forms between homologous chromosomes. A haploid cell can replicate by A gametophyte produces eggs and sperm by Cytokinesis generally occurs in
