alleryDNA fingerprinting, a quick method to distinguish individuals, was developed by:
AAlec Jeffrey
BIan Wilmut
CNorman Borlaug
DM. S. Swaminathan
Answer & Solution
Correct answer: A. Alec Jeffrey
1. DNA fingerprinting analyses unique DNA sequences to identify individuals.
2. The technique is credited to Alec Jeffrey in the text.
3. Ian Wilmut cloned Dolly the sheep, while Borlaug and Swaminathan are Green Revolution figures, so B, C and D are wrong.
4. Hence the answer is A.
