Question

According to Mendelism which character shows dominance?

• A. Green color in seed coat
• B. Terminal position of flower
• C. Green pod color
• D. Wrinkled seeds

Answer 1

The correct option is C

Green pod color

The correct option is C.

Explanation of correct option:

1. Gregor Mendel carried out artificial pollination/cross-pollination experiments on garden peas and proposed the laws of inheritance.
2. Mendelism or Mendel’s laws of inheritance are based on three principles- the law of dominance, the law of segregation, and the law of independent assortment.
3. In his experiment, Mendel studied seven characters comprising contrasting traits.
4. These contrasting traits include stem height (tall or dwarf), flower position (axial or terminal), seed coat color (green or yellow), pod color (green or yellow), seed shape (round or wrinkled), pod shape (inflated or constricted), and flower color (violet or white).
5. According to Mendelism, characteristics such as tall stem height, axial flower position, yellow seed coat, green pod, round seed, inflated pod, and violet flower show dominance.

Explanation of incorrect option:

Option A:

According to Mendelism, the green seed coat color is a recessive trait.

Option B:

Terminal flower position is a recessive trait according to Mendelism.

Option D:

Mendelism states that wrinkled seed is a recessive trait.

Final answer: According to Mendelism, the green pod color shows dominance.
