| Meiosis & Sexual Reproduction 1. Meiosis a. The phases b. Crossing Over 2. Sexual Development a. Sex determination (How does it work?) b. Sexual development 3. Life Cycles (Sexual versus non-sexual, or mixed) Standard 2a: Meiosis is an early step in sexual reproduction in which the pairs of chromosomes separate and segregate randomly during cell division to produce gametes containing one chromosome of each type. Standard 2b: Only certain cells in a multicellular organism undergo meiosis. | ||
