Vedclass · Answer

(D) Thomas Hunt Morgan and his colleagues worked with the fruit fly, $Drosophila$ $melanogaster$, to verify the chromosomal theory of inheritance. They chose $Drosophila$ because they could be grown on simple synthetic media in the laboratory, they complete their life cycle in about two weeks, and a single mating could produce a large number of progeny flies. Furthermore, there was a clear differentiation of the sexes, and many types of hereditary variations could be seen with low-power microscopes. Through these experiments, Morgan discovered the phenomenon of linkage, which describes the physical association of genes on a chromosome.

Thomas Hunt Morgan and his colleagues performed experiments on which organism to verify the chromosomal theory of inheritance and later demonstrated linkage?
