Question

Which scientist provided the first experimental proof of the Chromosomal Theory of Inheritance using Drosophila melanogaster?

Options

• Theodor Boveri

• Gregor Mendel

• Walter Sutton

• Thomas Hunt Morgan

Answer 1

Thomas Hunt Morgan provided the first experimental proof of the Chromosomal Theory of Inheritance in 1910 using fruit flies (Drosophila melanogaster). Morgan's elegant experiments, particularly his work on sex-linked inheritance and chromosome mapping, provided definitive evidence linking specific genes to specific chromosomes and confirmed the theoretical predictions of Sutton and Boveri.
