AReginald Punnett in 1902
BAlfred Sturtevant in 1913
CThomas Hunt Morgan in 1910
DBarbara McClintock in 1931
Answer & Solution
Correct answer: C. Thomas Hunt Morgan in 1910
1. Eye colour in Drosophila was one of the first X-linked traits identified.
2. Thomas Hunt Morgan mapped it to the X chromosome in 1910.
3. Sturtevant, working in Morgan's laboratory, built the first chromosome map in 1913.
4. McClintock and Creighton demonstrated crossover in corn in 1931, two decades later.
