The 3 Species That Break Genetics
Scientists have discovered a group of three closely related flowers that seem to break the laws of genetics. These mountain beardtongues are pollinated by either bees or butterflies, but not both, and that's the key to an incredibly...

Mendel Got Extremely Lucky (...or Maybe He Lied)
Science, while often the result of a stroke of genius, can just as easily be a stroke of extraordinarily good luck. Mendel’s work just happened to be a mix of the two.

Mechanisms that Increase Genetic Variation
Paul Andersen describes mechanisms that increase the genetic variation within a population. He begins by discussing how horizontal transfer can move genetic material between bacteria. Transformation, transduction, and conjugation in...

Advanced Genetics
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...

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...

Mendelian Genetics
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...

Mendel and Inheritance
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...

Why Do Some People Look More Like Their Grandparents Than Their Parents?
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...

Mendelian Genetics and the Laws of Heredity
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...

Mendelian Genetics and Punnett Squares
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...

Inheritance of X-Linked Genes
We all know that DNA is the molecule of heredity, but we didn't always know that. It had to be demonstrated empirically. As it happens, some of the first evidence put forth had to do with genes found on the X-chromosome of fruit flies,...
