Phases of Meiosis
In this video Paul Andersen explains the major phases of meiosis including: interphase, prophase I, metaphase I, anaphase I, telophase I, cytokinesis, interphase II, metaphase II, anaphase II, and telophase II. He explains how variation...

Mechanisms that Increase Genetic Variation
Paul Andersen describes mechanisms that increase the genetic variation within a population. He begins by discussing how horizontal transfer can move genetic material between bacteria. Transformation, transduction, and conjugation in...

Chromosomal Inheritance
In this video Paul Andersen describes genetics at the chromosomal level. He begins with a simple monohybrid cross as viewed through Mendelian genetics and then shows how genes are distributed through meiosis to possible gametes. This is...

Linked Genes
Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based punnett squares to explain why...

Animation of Meiosis
Demonstrate the cell division and phases of meiosis by showing this video clip. An animated cell splits as chromosomes line up and are pulled apart by spindles. Help your young biologists see just how meiosis works.
