Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...
Biology Corner
Human Genetics
Explore how our chromosomes work to define human attributes. A complete unit presentation includes topics such as genetic disorders, blood typing, and Punnet squares. Learners answer questions throughout the presentation to apply the...

Color Variation Over Time in Rock Pocket Mouse Populations
While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Roll of the Genes
Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...
