Drosophila Melanogaster Is a Suitable Research Subject for Developmental Genetics

Drosophila melanogaster is a suitable research subject for developmental genetics studies because:

A) the fly is large enough for many surgical procedures.
B) many developmental control genes observed in the fly are also present in humans.
C) flies are not subject to genetic mutations.
D) while flies are small and easy to house, they require specialized and expensive dietary requirements.
E) the control of fly development is unique and unrelated to human development.
