Pearson, as an active contributor to the biology learning community, is pleased to provide free access to the Classic edition of The Biology Place to all educators and their students.
The purpose of the activities is to help you review material you have already studied in class or have read in your text. Some of the material will extend your knowledge beyond your classwork or textbook reading. At the end of each activity, you can assess your progress through a Self-Quiz.

This BioCoach activity will help you review meiosis, the two successive divisions of a diploid cell of a sexually reproducing organism that result in four haploid progeny cells, each with half the genetic material of the original cell.
You will find information about the process of meiosis, and the relevance of meiosis to genetics. Animations show the process of meiosis in a dynamic way.
You can test your understanding of meiosis by using the Self-Quiz at the end of the module.
For comparison purposes, mitosis is the process of cell division in eukaryotes, in which the parental chromosome number is conserved in each of the daughter cells, while meiosis is a two-cell-division process in sexually reproducing eukaryotes that results in cells (typically gametes) with one-half the chromosome number of the original parental cell.
