In this list you will find animations, tutorials, articles, graphics relating to the following California Standards: Standard 2b: Only certain cells in a multicellular organism undergo meiosis. Standard 2a: Students know 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 2f: The role of chromosomes in determining an individual's sex. California Standards for Biology
