A hard review of high school genetics: Mendelian and non-Mendelian inheritance, meiosis, molecular genetics, Punnett squares, and pedigrees. Built for Grades 9-11. 25 ready-to-play clues, no prep needed. This is a Grades 9–11 Science review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Mendelian Laws, Non-Mendelian Traits, Chromosomal Basis, Molecular Genetics, Punnett & Pedigrees.
