Definition
We study the work of Gregor Johannes Mendel, who worked with pea plants to study heredity.
Why pea plants?
- They are easy to grow
- Have a visible set of characters
- Short life cycle, thus can study multiple generations in less time.
Characters of Pea Plants
| Characters | Dominant | Recessive |
|---|---|---|
| Flower Colour | Violet | White |
| Flower Position | Axial | Terminal |
| Seed Colour | Yellow | Green |
| Seed Coat | Round | Wrinkled |
| Pod Colour | Green | Yellow |
| Pod Shape | Inflated | Constricted |
| Plant Height | Tall | Short |
Experiments
No. 1
He first crossed one tall plant and one short plant → Law of Dominance
Then Self-pollinated the F1 Progeny → Law of Segregation
No. 2
He crossed two plants with two different traits and then eventually self-pollinated the F1 Progeny → Law of Independent Assortment
