Cell Division
Paul Andersen explains how cells duplicate through the process of cell division. Prokaryotic cells (like bacteria) duplicate through a process of binary fission. Eukaryotic cells (like you) duplicate body cells through mitosis and create...
Crash Course
The Reproductive System: How Gonads Go - CrashCourse Biology
Hank lets us in on the meaning of life, at least from a biological perspective - it's reproduction, which answers the essential question of all organisms: how do I make more of myself? So, sex, how does it work?

Population Modeling
Paul Andersen shows you how we can use a spreadsheet to model population changes. He begins with a brief discussion of populations and life cycles. He then shows you how you can model a single generation using a spreadsheet.

The Reproductive System
Paul Andersen starts with a brief description of asexual and sexual reproduction. He explains how meiosis ensures variation in the next generation. He describes the important structures in the male and female reproductive system. He...

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...

How Sex Became A Thing
We don't know which living thing was the very first to arrive at the totally revolutionary process that is sexual reproduction but we can follow the history of how (and why) sex became a thing.

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...

GCSE Biology - Sexual vs Asexual Reproduction - What is Asexual Reproduction? #71
How do organisms reproduce? Well it depends on the organism. We explore the two main types - sexual and asexual and consider the consequences of each.
