Instructional Ideas
- Purchase some PTC paper and host a paper-tasting activity to extend the lesson
- Create small groups and have them research a specific trait, such as tongue-rolling or detached earlobes
Classroom Considerations
- The resource begins to touch on Punnett squares and Mendelian genetics, so plan to follow up on these after the class has a good grasp on alleles and genes
- This video is hosted on YouTube
Pros
- The video is very engaging and interesting for all audiences
- Cute animated characters help convey genotypes and phenotypes
Cons
- None
