Drosophila

The simple but revolutionary organism Drosophila melanogaster has intricate properties that are studied to find its relations with human genes. Not only is D. melanogaster a model organism for its rapid growth, inexpensive culturing, and easy modifications, the Drosophila can provide more in-depth scientific analysis that can solve human diseases. The model organism D. melanogaster is studied to find ground-breaking research in neurology, sleep, cancer, and drug discovery. The multivariable…

Introduction: The Drosophila melanogaster, otherwise known as the common fruit fly has been a useful organism to the field of genetics. It has a relatively short generation time of approximately 10 days at 25 degrees Celsius, and yields a large amount of offspring. This results in large amounts of data over a short time period. In this lab, the purpose was to demonstrate how the Drosophila melanogaster is used in the field of genetics to study the inheritance of traits throughout the F1 and F2…

Evolution is defined as a change in allele frequencies from one generation to another generation with time. To test the evolution theory, Drosophila was chosen as a great experiment organism because of its short life cycle, rapid development, its small size and the large amount of breeding data can be produced. There are two types of allele of Drosophila observed which are ebony allele and wild-type allele. While wild type allele is dominant and easily found in nature, the ebony type is a…

This review article describes how the mating decision of Drosophila fruit flies is dependent of first the male’s choice to mate and then the female’s choice to accept or reject the male. The article simplifies the mating by the neurobiology behind the male’s choice and then the female’s choice. Furthermore, the article describes how males rely on chemical signals to detect suitable courtship objects and distinguish female flies from males. According to the article, males courtship is based on…

In addition to being small and easy to handle and store, D. melanogaster is inexpensive…

The Drosophila melanogaster has been a novel model organism for researchers for over a century studying various species at a molecular level. Because Drosophila has a short life cycle and easy to manipulate advocates Drosophila as a good model organism. The insight into molecular mechanisms in studying this species is why it has been used for such a long period. This organism is easy to manipulate to observe the changes over time, and because of this the variability among these species allows…

Drosophila melanogaster are often used as a model organism in laboratories due to the many advantages that the organism provides: short generation time, sexual dimorphisms, cost effectiveness and easiness to maintain, amongst others. The generation time of Drosophila is around 9 – 11 days, and phenotypes in men, such as sex combs, heavily pigmented abdomen, and shape of abdomen and size, makes of Drosophila melanogaster an effective organism to study. In Drosophila melanogaster, the males do…

Drosophila melanogaster, a species of common fruit flies, is widely used for biological research in studies amongst geneticists around the world. For many different reasons, these miniature organisms have become a favorite model organism for geneticists, biologists, physiologists, and many other scientists today, the obvious ones being their low cost, easy maintenance, ten-day generation time, and the fact that they produce large quantities of progeny. Besides these reasons, this species has…

1. What is the scientific name of fruit flies? The scientific name of fruit flies is Drosophila melanogaster. 2. Why are fruit flies used in scientific research? Fruit flies are used in scientific research because we, as humans, share 75% of the genes that cause diseases in us with them. This allows scientists to studying genes that exist in humans without actually experimenting on humans. In addition, it is not hard to take care of fruit flies and scientists can study them without…

the past six weeks of genetic lab we have been doing an experiment about fruit fly (drosophila melanogaster); we had the opportunity to learn more of how to distinguish between the male and female drosophila; one way that helps me was to look for the sex comb and the size. The purpose of this experiment was to learn more and be able to understand the Mendelian Genetics. We did an actual cross of fruit fly (drosophila melanogaster) such as the monohybrid, dihybrid, X-linked A, X-linked B and…
