Study Notes
Gregor Mendel
- First to study heredity
- Observed characteristics of pea plants
- Each characteristic occurs in two contrasting traits
- Example: Plant height (short/tall)
Traits
- Always produce offspring with that trait
- Example: All offspring with short stems
- Pure for one trait (not necessarily others)
- Example: All short stems but may have white or pink flowers
- Hybrid
- Offspring from parents with different traits
