Morgan's research led him to formulate the chromosomal theory of heredity and won him the Nobel Prize in Medicine in 1933.

At Columbia, Morgan began to study heredity with a team of students, experimenting with Drosophila ampelophila and Drosophila melanogaster, which proved Mendel's theories and enabled the principles of genetics to be determined. Morgan proved the reality of genes as bodily elements of specific location on chromosomes.
