What is the characteristics of Drosophila melanogaster?
It has a rounded head with large, red, compound eyes; three smaller simple eyes, and short antennae. Its mouth has developed for sopping up liquids (Patterson and Stone 1952). The female is slightly larger than the male (Patterson, et al 1943).
Is Drosophila a Diptera?
melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. The terms “fruit fly” and “Drosophila” are often used synonymously with D….
|Genus:||Drosophila Fallén, 1823|
Is Drosophila melanogaster a Dipteran fly?
Drosophila melanogaster is a species of fly (the taxonomic order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the “vinegar fly” or “pomace fly”.
Why is Drosophila melanogaster a model organism?
Genetic factors also make this fly an ideal model organism. D. melanogaster only has four pairs of chromosomes compared to 23 pairs in humans. This simplicity was one of the reasons why they were first used in genetic studies; Drosophila genes could be mapped easily to investigate genetic transmission.
How do you identify a Diptera?
Insects in the order Diptera have only one pair of wings (2 wings total). Their antennae are generally shorter than their head. Insects in the order Neuroptera have long, thin, cylindrical bodies. Their two pairs of wings are generally the same size.
Why are Drosophila melanogaster used in genetics?
Drosophila melanogaster, known colloquially as the fruit fly, remains one of the most commonly used model organisms for biomedical science. These tools allow researchers to maintain complex stocks with multiple mutations on single chromosomes over generations, an advance that made flies the premier genetic system .
Why is Drosophila melanogaster used in genetic studies?
Genetic manipulation melanogaster only has four pairs of chromosomes compared to 23 pairs in humans. This simplicity was one of the reasons why they were first used in genetic studies; Drosophila genes could be mapped easily to investigate genetic transmission.
Why is Drosophila a model organism for genetics?
There are many technical advantages of using Drosophila over vertebrate models; they are easy and inexpensive to culture in laboratory conditions, have a much shorter life cycle, they produce large numbers of externally laid embryos and they can be genetically modified in numerous ways.

Does demography shape genetic variation in Drosophila melanogaster?
Demography and natural selection have shaped genetic variation in Drosophila melanogaster: a multilocus approach. Genetics165:1269–1278. [PMC free article][PubMed] [Google Scholar] Haddrill, P. R., K. R. Thornton, B. Charlesworth and P. Andolfatto, 2005.
Do African Drosophila populations harbor more variation than non-African populations?
African Drosophila populations were shown to harbor substantially more variation than non-African populations (Begunand Aquadro1993; Irvinet al.1998; Hamblinand Veuille1999; Kaueret al.2002), hence, they are much better suited to infer the long-term effective population size of both species.
Why are Drosophila melanomas used in genetic studies?
Drosophila melanomas are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled, they have a short life cycle and they are easy to keep large numbers such as the confined spaces of a laboratory or classroom.
