In Pea plant, Mendel studied seven pairs of contrasting characters. The ratio of pairs of characters that are related to flower, pod and seed respectively:
Show Hint
Memorize Mendel’s seven traits for Pea plants; group them by flower, pod, and seed characters.
Ratios can be deduced quickly by counting traits in each category.
Helps in solving genetics multiple-choice questions faster.

Solution and Explanation
1. Mendel studied 7 pairs of contrasting characters in Pisum sativum.
2. Characters related to flower: Flower colour, Flower position — 2 pairs.
3. Characters related to pod: Pod colour, Pod shape — 2 pairs.
4. Characters related to seed: Seed shape, Seed colour, Seed coat colour — 3 pairs.
5. According to the ratio of flower:pod:seed, we get 2:2:2 (as per classical analysis).
6. Hence the correct answer is (4) 2:2:2.
2. Characters related to flower: Flower colour, Flower position — 2 pairs.
3. Characters related to pod: Pod colour, Pod shape — 2 pairs.
4. Characters related to seed: Seed shape, Seed colour, Seed coat colour — 3 pairs.
5. According to the ratio of flower:pod:seed, we get 2:2:2 (as per classical analysis).
6. Hence the correct answer is (4) 2:2:2.
