In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA. Then, learners decode the DNA recipe to reveal the physical traits of their dog and create a final drawing of the organism. Learners discover that differences in the DNA recipe lead to different traits by comparing their DNA recipes and dog drawings with the rest of the group to note similarities and differences. This guide features handouts for learners in English and Spanish.
