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?

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...

Gene Linkage and Genetic Maps
We just learned about X-linked genes, but what about gene linkage in general? If two genes are on the same chromosome, we can say that they are linked. Are they always inherited together? Can the alleles rearrange in some way? Well don't...
