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...

Our physical appearance is significantly influenced by our genes, which are inherited from our parents, who in turn receive their genetic material from their own parents. When your genetic makeup closely mirrors that of your...

Dive into the fascinating world of genetics to understand how traits like tongue rolling are passed from parents to children. Learn about Gregor Mendel, the father of genetics, and his groundbreaking experiments with pea plants that...

In this video, we'll explore what DNA is, its role in life as we know it, and how it shapes every organism on our planet. From the eye color you inherited to the stripes on a tiger, learn how the 'blueprint of life' guides the...

For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all...

The genetics with most illnesses do not follow Mendelian genetics. Mendelian genetics is what you learned in science class where you could predict a certain trait based on what traits your parents have. Bipolar disorder and...

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...

In this detailed video, we'll walk you through dihybrid crosses, Punnett squares, and the often-discussed 9:3:3:1 ratio. Get ready to dive deep into the world of genetics! This step-by-step guide to dihybrid crosses using...

This video will show how to set up and solve everyone's favorite 16 square Punnett square.

Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out...

How a 19th century Austrian monk explained the rules of genetic inheritance before anyone even knew genes existed. Biology - Cells And DNA - Learning Points. Before the discovery of genes, Austrian monk Gregor Mendel described three laws...

Hank and his brother John discuss heredity via the gross example of relative ear wax moistness.

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...

This week, scientists have managed to make tear gland organoids that cry, and have also found a bunch of new genes involved in eye color!
