10. Mendel noted that the size of pea plants varied. He cross-bred these pea plants to find some surprising results.

12. Mendel’s cross between tall pea plants yielded all tall pea plants. His cross between small pea plants yielded all small pea plants. Mendel’s cross between tall pea plants and small pea plants yielded all tall pea plants. X = x = X = F 1 GENERATION P GENERATION
