Instructional Ideas

• After the video, allow learners to further explore the examples given in the video or other examples of variation
• Explore further the work of Christina Cheng and gene cloning, referenced in the video

Classroom Considerations

• To watch the video, you need a computer, projection system, and access to the Internet
• Part 12 in a series of 37

Pros

• Video explores two different ways for cells to vary from one another
• Great example of possessing one gene of sickle-cell anemia and how that helps with malaria
• The referenced movie, Multiplicity, engages high school learners

Cons
