This Genetic Drift 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.
- Further research the bottleneck effect on northern elephant seals and share findings with the class
- Video assumes students understand alleles, dominant/recessive genes, and allele frequency (Hardy-Weinberg)
- Resource is the eighth in a collection of 18 videos
- Video provides links to a concept map, slideshow and two review worksheets
- Utilizes high-quality diagrams and photographs to help teach the information
