Mitosis Interphase - DNA is copied Prophase - chromatin shortens, centrioles move to opposite ends,  Metaphase - chromatids line up Anaphase- daughter chromosomes split and go to each end Telophase and Cytokinesis - cell cleaves at the cleavage furrow, nuclear envelope re-forms (animal cell - cleavage furrow, plant cell - cell plate)   Meiosis I Interphase -  DNA is copied Prophase I -  centrioles move to opposite ends, CROSSING OVER OCCURS during synapse Metaphase I -  chromatids line up Anaphase  -  the chromatids move to opposite ends Telophase I  -  cell splits at the cleavage furrow,  and Cytokinesis --no DNA replication occurs between meiosis I and meiosis II-- Meiosis  II Prophase II -  spindle apparatus forms Metaphase II -  sister chromatids line up, they are not genetically identical b/c of crossing over Anaphase II -  chromatids move to opposite ends Telophase II  and Cytokinesis  -  nuclei form, cell cleaves, four daughter cells are genetically distinct   Mendel Law of Independent Assortment  - each pair of alleles segregates independently of other pairs of  alleles during gamete formation Law of Segregation  - each allele in a pair separates into a different gamete during gamete  formation The laws of probability govern Mendelian inheritance. The multiplication and addition rules apply to monohybrid crosses.
