Solution
The correct option is D Drosophila melanogaster
Morgan worked with the tiny fruit flies, Drosophila melanogaster. Drosophila was a good model for gentic studies due to many reasons.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 a large number of progeny flies. Also, there was a clear differentiation of the sexes – the male and female flies are easily distinguishable. In addition, it has many types of hereditary variations that can be seen with low power microscopes.
