[Crazy Traits guide]

Crazy Traits is a fun and innovative tool for helping students learn about genetics and evolution. Through a series of games and activities, students learn that the traits people and animals inherit from their parents are based on chance. Alleles, genotypes, and phenotypes are also explored. Students flip special coins that represent each parent, record their outcomes, and build a "Crazy Creature" based on the results. Special Environment Cards add to the excitement, allowing students to explore how environment influences the traits in a population.
