Dragon Genetics

This activity explores the relationship between genotype and phenotype, using both sex-linked and autosomal dominant and recessive traits. By manipulating alleles (genotype), you create corresponding changes in the dragon's physical appearance (phenotype).

There are 2 activities for students to explore with visualizations:

Additionally, this kit includes two teacher guides for additional resources and feedback on the set up and delivery of this curriculum.

Also, the Concord Consortium Links to an external site. has a dynamic simulation regarding this experiment that expands the content -- Geniverse is free, web-based software for high school biology that engages students in exploring heredity and genetics by breeding and studying virtual dragons. Interactive models, powered by real genes, enable students to do simulated experiments, generate realistic and meaningful genetic data and win star ratings for efficient experimentation. Students can sign up for 4 weeks free or play as a guest.
