This lesson introduces students to the relationships between chromosomes, genes, and DNA molecules. Using the example of a strawberry, it also provides activities that clearly show how changes in the DNA of an organism, either naturally or artificially, can cause changes. Grades 9-12

This lesson allows students to apply the concept of Mendelian genetics and learn about the double muscling trait found in cattle. Students will apply their knowledge of genetics and Punnett squares to calculate the probability of genotypes and use a pedigree chart. Grades 9-12

Explore six scientific processes that can be used in plant breeding to modify the genotype of a plant in the pursuit of desired characteristics.

Students learn about DNA by extracting it from strawberries. Students also analyze the similarities and differences of their extraction process to those on Genetic Engineering: The Journey of a Gene. Students learn how genetic testing (including DNA extraction) is useful in breeding new varieties of strawberries. Grades 9-12
