Hidden Genes

🧬 Why do traits appear in children that their parents didn't show? Genes come in pairs, and yellow Y masks green y. A pea can look yellow while hiding a green gene inside! That makes two physical traits but three gene combinations. 🔲 With Punnett squares, pick the parents' genotypes and four offspring boxes fill in automatically. When two yellow parents produce a green offspring, hidden genes met — showing a 3 yellow : 1 green ratio. 🩸 With blood types, discover how A, B, and O genes create four blood types. Find out how two type A parents can have a type O child! Built with code — remix it to try other traits!
