The way for knowing how many genes control development in an organism like Drosophila Introduction: The Drosophila melanogaster is the widely used model organism in the field of genetics and developmental biology. It is also called as the fruit fly. It is suitable for laboratory studies since it carries only four chromosomes and hence creating a loss of function and gain of function of these genes is very easy. There is various reason for using this as a model organism which includes low cost, morphology is easy to identify, small in size, genetic crossing can be done, etc.
