Tutorial examines how a cell divides to make two genetically identical cells and explores the four basic phases: prophase, metaphase, anaphase, and telophase.

In this tutorial students will learn how meiosis reduces chromosome number by half and become familiar with crossing over, meiosis I, meiosis II, and genetic variation.
