Which of the following pair of contrasting traits was not studied by Mendel?
- Pink and white flowers
- Inflated and constricted pods
- Axial and terminal flowers
- Green and yellow pods
The Correct Option is A
Solution and Explanation
(1) Pink and white flowers
This pair of contrasting traits was not studied by Mendel. Mendel focused on traits that exhibited clear dominant and recessive relationships, and pink flowers do not fit this model as they often result from incomplete dominance.
(2) Inflated and constricted pods
This pair of contrasting traits was studied by Mendel. He observed that inflated pods were dominant over constricted pods.
(3) Axial and terminal flowers
This pair of contrasting traits was studied by Mendel. He observed that axial flowers were dominant over terminal flowers.
(4) Green and yellow pods
This pair of contrasting traits was studied by Mendel. He observed that green pods were dominant over yellow pods.
Conclusion
The correct answer is (1) Pink and white flowers. This pair of contrasting traits was not studied by Mendel because it does not fit the simple dominant-recessive model that Mendel focused on.
