Evolution: It's a Thing - Crash Course Biology
Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

How the First Americans Got There
This week, researches published a genetic analysis of the 11,500-year-old remains of a baby found in Alaska, near where the first Americans crossed the Bering land bridge. That analysis has answered some lingering questions about human...

TED-Ed: Where do genes come from? - Carl Zimmer
When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...

Having Six Fingers Is a Dominant Trait
Genetics are extremely complicated—so complicated that having an extra finger or toe, for example, is exceedingly rare despite it being caused by a dominant gene.

Genetics and The Modern Synthesis: Crash Course History of Science
Remember how Darwin and Mendel lived around the same time, but everyone forgot about Mendel until 1900, and even then biologists saw Darwinism and Mendelism as two competing grand theories about how life works? Well, in this episode of...

Genetics - Lost and Found: Crash Course History of Science
Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

Chromosomal Genetics
Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked genes...

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...
