Drosophila Melanogaster In The Fruit Flies

From the primary literature, briefly summarize two studies that have used Drosophila as a model organism in a genetic or evolutionary context (Twenty Five Marks).

The aggressive behaviour of the Fruit flies (Drosophila melanogaster) have been observed in a study to see the reaction of various neurobiological factors. Several techniques are used in the study including behavioural and genetic techniques. In the brain of the Drosophila melanogaster, neurotransmitters dopamine and octopamine as well as mushroom bodies (found in a certain part of the brain) have an overwhelming impact on aggressive behaviour manifestation in the fruit flies. Serotonin a neurotransmitter which can be found in a few places in the human body such as the brain and blood platelets can affect the happiness of people actually had no influence on the behaviour of the Drosophila melanogaster. In conclusion, that the Fruit flies (Drosophila melanogaster) can prospectively become a model organism for the neurobiology of aggression.

The Drosophila are also an economically viable model that has an adaptable and widespread collection of techniques/procedures for process such as gene functional analysis and gene identification. Flybase is a database of the Drosophila and it contains a wide-ranging assortment of flies which includes mutant strains of flies. Resources such as the flybase make genetic screens (used to identify organisms with interesting phenotypes) more straightforward. Furthermore, it has been established that the fruit flies (Drosophila) have been successfully been a part of research in neuropharmacology. Chemical genetic screening on a fruit fly model of the X syndrome was demonstrated
