Drosophila melanogaster is a very useful model organism and has been used for over 80 years in the study of inheritance. Dros0phila have giant, polytene, chromosomes which make chromosomal processes easier to study under the microscope. Specific changes in the organisms hereditary information were found to exactly correlate to the alteration or loss of specific giant chromosome bands. This provided proof that units of hereditary information are carried on chromosomes. The Drosphila has also been used to gain further understanding of embryonic development.
