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,...

Hardy-Weinberg Principle
After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable...

Natural Selection
Between 1968 and 2002, the total number of peppered moths decreased by almost two thirds, although scientists do now know why. In the 10th video of the series, the instructor defines evolution as any changes to a gene pool. Scholars then...

Solving Hardy-Weinberg Problems
What is a gene pool? What do gene pools have to do with the Hardy-Weinberg formula? How was this formula derived? After viewing a video that introduces these concepts, young scientists determine p and q values and then work sample...

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...
