The fruit fly Drosophila melanogaster is an important model system for studying inheritance in animals and genetic control of animal development, including humans. If researchers ultimately want to understand a biological process in humans, why might they want to study the process in fruit flies first? (Select all that apply.)

A) Fruit flies are relatively easy to genetically manipulate and to isolate mutations.
B) Fruit flies have short generation times and produce relatively large numbers of progeny.
C) Fruit flies have simpler genomes than do humans.
D) Fruit flies share all important physiological and developmental processes with humans.
E) Fruit flies are small and easy to raise.
