Correct Answer
(C) Alfred Sturtevant
Solution & Explanation
Answer: (C) Alfred Sturtevant Solution: Alfred Sturtevant, a student of Morgan, used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes and mapped their positions on the chromosome. Morgan coined the terms linkage and recombination, but it was Sturtevant who applied recombination frequency to gene mapping. NCERT Reference: NCERT Class XII, Ch 4, p.67, lines 047-050: "His student Alfred Sturtevant used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes and ‘mapped’ their position on the chromosome."
