Page 10 of a biology study guide focusing on Mendel's laws of heredity and meiosis, with exercises and a table for analyzing genetic traits.

1. Mendel crossed purebred tall plants with purebred short plants.
2. All offspring were tall.
3. When he self-pollinated the tall offspring, both tall and short plants appeared in the next generation.
4. He concluded that traits are inherited as discrete units (genes), and some alleles are dominant while others are recessive.
5. He formulated the Law of Segregation: each organism has two alleles for each trait, which separate during gamete formation.
6. He also formulated the Law of Independent Assortment: alleles for different traits are distributed to gametes independently of one another.
7. His work laid the foundation for modern genetics by introducing the concept of heredity through genes.
