10.1 Meiosis

10.1 meiosis from Bob Smullen

Here are some fantastic animated tutorials about Meiosis from McGraw Hill Education – how Meiosis works, the stages of Meiosis, Meiosis I, Meiosis II, Crossing-over, Independent Assortment & unique features of Meiosis.

From Sinauer Associates comes an animated, narrated tutorial on Independent Assortment which also includes a quiz; there’s also one on Independent Assortment & gamete diversity (with a quiz) and one on mistakes in meiosis – nondisjunction.

Mr. Andersen uses chromosome beads to simulate both Mitosis and Meiosis:
