This Genetic Drift instructional video also includes:
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, demonstrating how they drift apart. In the end, pupils see how the bottleneck effect drastically changed the northern elephant seal population.
