| Why did Mendel choose peas? |
|
Definition
1. Peas have several characters available for comparisons among plants
2. The characters are variable such that there are different “traits “ or “states” for each character (e.g., different colors for flower color or pea color; different shapes for peas)
3. Character variation was “either-or” instead of “more-or-less”. No blending
