Genetic Drift
Survival is a game of chance, catch my drift? Examine the factors that influence genetic drift with an entertaining video from a large biology playlist. The resource covers the myriad conditions that come into play when a species...

Disruption of Genetic Equilibrium
Could a population stay the exact same over time with no change in allele frequencies? The video explains the Hardy-Weinberg equilibrium theorem and the assumptions it requires. It discusses mutation, migration, gene flow, genetic drift,...

Genetic Drift
Male northern elephant seals grow to be 13 feet in length and can weigh up to 4,500 pounds. In the video, scholars explore genetic drift in a population through a simulation. The instructor shows allele frequencies changing over time,...

Population Genetics: When Darwin Met Mendel
Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.
Khan Academy
Khan Academy: Influenza Pathology: Flu Shift and Drift
Learn how Type B Influenza virus has genetic drift, whereas Type A Influenza virus has genetic drift AND shift. Rishi is a pediatric infectious disease physician and works at Khan Academy. [7:44]
Khan Academy
Khan Academy: Influenza: Genetic Shift and Drift
The flu virus has the unique ability to change in two different ways, causing genetic shift and drift. Learn exactly how these two mechanisms differ from one another. [4:55]
Khan Academy
Khan Academy: Antigenic Shift and Drift
A video discussing the unique ability of the flu virus to change in two different ways. The change causes either genetic shift and drift. [4:55]
Bozeman Science
Bozeman Science: Genetic Drift
Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...
