The Drosophila model refers to the use of the fruit fly Drosophila melanogaster as a model organism in biological research. Drosophila has been used extensively in genetics and developmental biology research due to its short generation time, high fecundity, and well-characterized genetic tools. Researchers use Drosophila to study a wide range of biological processes, including development, behavior, neurobiology, and disease modeling. The use of Drosophila as a model system has provided valuable insights into fundamental biological processes and has contributed to many important discoveries in various fields of biology.
