Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their...

Join us as we dive into the fascinating world of genetics, guided by the Father of Genetics himself, Gregor Mendel. We'll explore the laws of heredity Mendel formulated from his groundbreaking experiments with pea plants and learn how...

Paul Andersen previews the information in the genetics unit. He defines the central dogma of biology and explains how DNA creates an RNA transcript that is used to translate proteins. He differentiates between mitosis and meiosis. He...

Paul Andersen explains important concepts that can not be explained by simple Mendelian genetics. He begins with a discussion of polygenic inheritance and uses a simulation on height to show how a bell shape curve of phenotypes is...

Electrophiles are electron-poor species, often possessing a positive charge or an empty orbital, making them highly reactive in seeking electron pairs from nucleophiles. Common examples include positively charged ions like

𝐻+H + ...

We've already learned about Mendelian genetics, which taught us about dominant and recessive alleles and the laws that govern their inheritance. But things are not always so simple. There are situations that go beyond this basic...

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...

The 13 colonies were all part of the British Empire, but they had many differences, from colonists' views on religious freedom to how they educated their children.

Ready to review how to do different types of Mendelian and Non-Mendelian Punnett square problems with The Amoeba Sisters? This video reviews one-trait / monohybrid crosses, two-trait / dihybrid crosses, incomplete dominance, codominance,...

When you think "parasite," you might think of leeches or some nasty tape worm, but there are some that can live inside your very own cells.

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

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...

Paul Andersen shows you how to use the rules of multiplication and addition to correctly solve genetics problems. The rule of multiplication can be applied to independent events in sequence. The rule of addition can be applied to...

One of the most powerful tools the President of the United States has is the veto - but what is it and how has it evolved over time?

Welcome back to the Fluctus Channel, as we explore the evolution of U.S. recovery operations, uncovering how complex missions have adapted over time to retrieve, repair, and protect critical military assets in the most...

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...

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.

Graduate Research Fellow Amy Battocletti is a Navy veteran who was awarded a Graduate Research Fellowship in 2014. She’s a doctoral candidate in biology at Georgetown University conducting research on the impact of genetic variation...

Study after study affirms that doctors treat their patients differently, depending on the patient's race. Minority patients get different diagnoses, different treatments, and are often subject to being stereotyped by their physicians.

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...

Genetics | Dihybrid Crosses (Example 1)

Paul Andersen reviews the concepts discovered by Gregor Mendel.

Hank brings us the story of Gregor Mendel, the Austrian monk who, with the help of a garden full of pea plants, discovered the fundamental properties of inheritance and paved the way for modern genetics. He also gives us the dirt on a...
