It goes through four stages in its life cycle. Thousands of these genes were entirely new to research and their functions remain to be determined. The life cycle can be completed within 2 weeks.
Commonly known as a fruit fly or vinegar fly Drosophila melanogaster is one of the most prevalent flying insects. Adult SWD are small 116 to 18 in long 23 mm with red eyes and a light brown thorax and abdomen. One species of Drosophila in particular Dmelanogaster has been heavily used in research in genetics and is a common model organism in developmental biology.

Tife cycle of Drosophila melanogaster comprises four successive stages namely egg larva pupa and adult. Melanogaster and related species as model systems is their particularly short life cycle which allows for the rapid generation of large numbers of progeny to use in genetic crosses Ashburner 1989In D. Work by Thomas Hunt Morgan 1866-1945 and his students at Columbia University at the beginning of the twentieth century led to great discoveries such as sex-linked inheritance and that ionising radiation causes mutations in genes.

Life cycle of Drosophila melanogaster Drosophila melanogaster exhibits complete metamorphism meaning the life cycle includes an egg larval worm-like form pupa and finally emergence eclosure as a flying adult. Eight days in the egg and larval stages and six. Because flies rapidly discover a body and their development times are predictable under particular environmental conditions the time of death can be calculated by counting back the days from the state of development of flies living on the corpse.
