Question

Write a note on seven contrasting traits studied by Mendel in pea plants.

Hint:

Mendel’s seven traits include height, flower position, pod shape/color, seed shape/color, and flower color.

Answer 1

Gregor Mendel studied seven contrasting traits in pea plants:

1. Plant height: Tall (T) vs Dwarf (t)
2. Flower position: Axial (A) vs Terminal (a)
3. Pod shape: Inflated (I) vs Constricted (i)
4. Pod color: Green (G) vs Yellow (g)
5. Seed shape: Round (R) vs Wrinkled (r)
6. Seed color: Yellow (Y) vs Green (y)
7. Flower color: Purple (P) vs White (p)

Mendel selected these traits because they exhibited clear dominant and recessive characteristics and followed predictable inheritance patterns.
