| Tutorial |
| · Animation and description of phases of meiosis |
| |
| 1. Mitosis |
| · Stages of cell cycle |
| · "c" vs "n" |
| · DNA replication, sister chromatids, homologous chromosomes |
| · Mitotic division phases |
| · Alleles on sister chromatids |
| · Drag and drop chromosomes to emulate mitosis |
| |
| 2. Meiosis |
| · Consequences of sexual reproduction without meiosis |
| · Drag and Drop chromosomes to emulate meiosis I |
| · Drag and Drop chromosomes to emulate meiosis II |
| · Number of gametes formed |
| · Phases of meiosis, values of c, n |
| · Karyotypes |
| · Sex chromosomes |
| |
| 3. Independent Assortment |
| · Drag and Drop two pairs of chromosomes to emulate meiosis I |
| · Gametes formed during meiosis II |
| · Linkage: independent assortment of chromosomes not necessarily markers |
| |
| 4. Microscopy |
| · Mitosis vs meiosis |
| · "c" vs "n" |
| · haploid vs diploid |
| |
| Problems |

| |
| 3. X linked dominant trait (Vitamin D rickets) |
| · Dominant vs recessive |

| |
| 4. X linked common recessive trait (Red green colorblindness)
and Sickle cell anemia (autosomal recessive) |
| · Independent Assortment |
| · Probabilities |
| |
| 5. Nondisjunction |
| · Colorblindness and Turner syndrome |
| · Colorblindness and Klinefelter syndrome |
| · Identify parent where nondisjunction occurred |

| · White eyes in flies |
| · Sex determination in flies |
