2. Understand how meiosis can create new combinations of alleles on a  single chromosome D.  Diagram  the major events in meiosis for a diploid organism (see Figure 12.2),  labeling  each stage with “n” or  2n E.  Describe  the fundamental differences between mitosis and meiosis (Fig 12.5  and Table 12.3) F.  Explain  how it is possible for the offspring of a single parent to have different  combinations of alleles that are not present in either parent 3. Understand how chromosomal dynamics during meiosis create new  combinations of chromosomes A. Trace  on a diagram maternal and paternal alleles into gametes 4. Understand how the combination of meiosis and fertilization (i.e., sexual  reproduction) results in a unique genotype and phenotype B.  Explain  why an offspring almost invariably is not genetically identical to its  parents
