Study Notes
Mendel's Experiments
- Mendel used pea plants (Pisum sativum) for his plant breeding experiments.
- He studied the characteristics of pea plants, including stem length, seed shape, and flower position.
Key Concepts
- The term "dominant" was used to describe the characteristic that showed up in the F1 generation.
- Alleles show segregation during meiosis.
F2 Generation Ratio
- In the monohybrid cross of tall plants x dwarf plants, a ratio of 3:1 was obtained in the F2 generation.
Mendel's Work
- Gregor Mendel studied the inheritance of characteristics in pea plants in the middle of the 19th century.
- He studied 7 pairs of contrasting characteristics.
F2 Generation Findings
- In the second filial generation, Mendel found a 3:1 ratio of dominant to recessive traits for flower position.
