DNALC Live: Mutant Organisms

Join the chat on YouTube

In this lab activity students will observe genetic traits in Drosophila melanogaster, a common species of fruit fly, that is used as a model organism in genetic research. Through a comparison of wild-type and mutant strains of Drosophila, participants will observe first-hand how mutations in DNA can affect the traits of a living thing, and draw conclusions about the role that mutations play in natural selection, evolution and genetic disease.

Participants will:

• Observe genetic traits in Drosophila fruit flies
• Describe the connection between genes and traits
• Understand the important role mutations play in all living things

Audience: Grades 5-8
Duration: 45 minutes
