Working in small cooperative groups, students use letters on red and blue tiles representing female and male alien parents to build Punnett Squares for monohybrid and dihybrid crosses.
Crossing a heterozygous yellow-eyed alien with a pink-eyed alien, students solve genetics problems and can work out their own parent scenarios. Developed by Cindy Dawson-Willis, the kit includes materials for 15 student groups and instructions.
