(B) Morgan

Solution & Explanation

Answer: (B) Morgan Solution: Sutton and Boveri proposed the chromosomal theory of inheritance, but its experimental verification was carried out by Thomas Hunt Morgan and his colleagues using the fruit fly Drosophila melanogaster. Their work led to the discovery of the basis for the variation produced by sexual reproduction. NCERT Reference: NCERT Class XII, Ch 4, p.67, lines 013-016: "Following this synthesis of ideas, experimental verification of the chromosomal theory of inheritance by Thomas Hunt Morgan and his colleagues, led to discovering the basis for the variation that sexual reproduction produced."
