The Individual Who is Credited with Discovering Genetic Linkage in Drosophila

Question

The individual who is credited with discovering genetic linkage in Drosophila is ________.
A) Thomas Hunt Morgan
B) Gregor Mendel
C) Alfred Sturtevant
D) Barbara McClintock

Accepted Answer

Thomas Hunt Morgan is credited with discovering genetic linkage in Drosophila through his experiments in the early 1900s. He observed that certain traits in fruit flies were consistently inherited together, suggesting that they were linked on the same chromosome. Morgan also proposed the idea of crossing-over between homologous chromosomes during meiosis, which further explained the inheritance patterns he observed.
