Answer & Solution

Correct Answer

(C) T.H. Morgan

Step-by-step Solution

Detailed explanation

(c) : Linkage is the phenomenon ofcertain genes staying together during inheritance through generations without any change or separation due to their being present on the same chromosome. Linkage was first suggested by Sutton and Boveri \((1902-1903)\) when they propounded the famous “chromosomal theory of inheritance.” Bateson and Punnett \((1906)\) while working on sweet pea found that the factors for certain characters do not show independent assortment.However, it was Morgan \((1910)\) who clearly proved and defined linkage on the basis of his breeding experiments in fruit fly (Drosophila melanogaster).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
