EarthRef.org Digital Archive (ERDA) -- Gummy Bear Genetics -- Teacher Information

Description
Using gummy bears, students explore the basics of population genetics and the connections between genetics and natural selection. Students are also introduced to the concept of incomplete dominance. Students will choose two initial breeding pairs from their bags. Then, following the rules of gummy bear inheritance, the students will continue to choose and predict the offspring based on the characteristics of the original breeding pairs. This activity emphasizes the randomness inherent in genetics. Also, students will practice using Punnett squares and review phenotypes and genotypes.
