Drosophila melanogaster, commonly known as the fruit fly, is a widely used model organism in genetics and developmental biology research. This tiny insect has a short life cycle, easily controllable genetics, and a well-annotated genome, making it an ideal organism for studying various biological processes. Researchers use Drosophila melanogaster to investigate topics such as gene expression, development, behavior, and evolution. Studies in Drosophila have led to important discoveries in genetics, such as the identification of genes responsible for development and diseases. This model organism continues to be a valuable tool for understanding fundamental biological processes.
