Crazy Chromosomes

[Students with equipment]

[Crazy Chromosomes guide]

Take your study of genetics to the next level. Crazy Chromosomes helps students make the connection between DNA, genes, chromosomes, and phenotypes. Use these colorful manipulatives to build sets of chromosomes, model gamete formation through meiosis, and model fertilization. Crazy Chromosomes is designed to work in tandem with the Crazy Traits heredity module (available separately). Build a diploid set of chromosomes for a “crazy creature.” Then, model how gametes are formed and combine them to produce genetically diverse offspring.
