Morgan worked with the tiny fruit fly, Drosophila melanogaster to prove the chromosomal theory of inheritance.

The fruit flies were found very suitable for such studies. They could be grown on simple synthetic medium in the laboratory. They complete their life cycle in about two weeks, and a single mating could produce numerous progeny flies. Also, there was a clear differentiation of the sexes – the male and female flies are easily distinguishable. Also, it has many types of hereditary variations that can be seen with low power microscopes.
