Pros And Cons Of The Fruit Fly

Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic.

In the last century, we human beings have discovered copious amounts about our own biochemistry: from genetics to development, behaviour to the origin of species, and evolution to aging. The reason many of these biological findings have been discovered is as a result of Drosophila melanogaster (the binomial nomenclature for the fruit fly) . Astonishingly, the fruit fly has been the tiny test subject from which some of the 20th century's greatest biological discoveries have arisen. In fact, crucial information such as the dangers of radiation, the principles of heredity and the causes and cures for many diseases are all built on the foundation of fruit fly research. Subsequently, I believe the greatest biological discovery of the 20th century

Drosophila melanogaster may just be small little fruit flies that feed on rotten fruit but this little creature happens to be one of the most valuable organisms in understanding genetic research. The D. melanogaster are commonly used in studying genetic traits because they are useful, small and have an extremely short life cycle (6). Our experiment shows precisely how D. melanogaster are used to identify mechanisms of transmission genetics in eukaryotes. Simple parental crosses were done to obtain both F1 and F2 generations. This was done so we could determine if the apterous (a wingless phenotype) and the sepia (dark brown) eye color of the fruit flies follows Mendelian inheritance or not. Our F1 generation displayed all offspring with red-eyes and wings; which follows Mendel’s principles. Our hypothesis is that our experiment will follow the classic inheritance patterns because the sepia traits and the wing traits display a dominant/recessive pattern in the D. melanogaster (4). If our hypothesis is correct, then we predict to see an entire F1 generation of red eyed fruit flies with wings and an F2 generation of 9 normal

At the university of chicago genetically modified animals containing the recovered genes from their ancestors are being made. The genes of fruit flies are being altered to contain an alcohol dehydrogenase gene which existed in them 4 million years ago. The goal of the experiment is to locate the genes that influence adaptations in animals, according a graduate student working on the project. Since the species of fruit fly used in the experiment, D. melanogaster are better at tolerating and breaking down alcohol, which researchers believe is because of the Adh gene they separated the ancient gene and gave it to other species. In the results the newer Adh gene and older one had little differences and both groups of flies were able to break down and survive in alcohol at the same level.

According to Grant et al. (2016) Drosophila melanogaster are also one of the very first organisms to have the sequence of their DNA determined. These flies are very easy to keep in large numbers as well. Another reason that Drosophila melanogaster are a great model organism to use is that the female flies can lay many eggs at once which results in more flies to count for data tables and will give better data results (“Why use the fly in research?”, 2017). Drosophila melanogaster are used often in Genetics because of how unique they are. There are different types of flies which make it easier to distinguish which characteristics are dominant, recessive, and whether or not they are due to gene linkage. Drosophila melanogaster are also used because they are small and cheap. It is noticed when observing different types of Drosophila melanogaster that female flies tend to be larger than male flies. It is also noted that male flies tend to a solid black area at the bottom of their abdomen which is known as the “tergites” (Arrogant Scientist,

Drosophila melanogaster commonly known as a fruit fly is an oviparous animal with a short generation time of approximately two weeks, during this time the insect hatches into a larva and goes through the developmental larval instar stages, and finally evolves into an adult fly. This species has become an important resource for biologists to better understand different organisms, such as other insects, and even humans. By understanding a simple living organism such as a fruit fly, researchers have been able to comprehend more complex organisms and their behaviors, brain processes, development and other important details. Some examples of the previous research done on this species have provided information about the sense organs in animals

Drosophila melanogaster is a species of fly in the family Drosophilidae. The species is known generally as the common fruit fly or vinegar fly. The larvae was injured to isolate hemolglobin for the trials. It was then added to the substrates, the buffer and used within diffeent variables. Two types of Drosphila Melanogaster used within the Assays are Wild Type and Black Cell. Wild Type fruit flies are yellow-brown, with brick-red eyes and transverse black rings across the abdomen. Black cells are a mutation causing spontaneous melanization of Drosophila crystal cells, a hemocyte cell type producing phenoloxidases. The phenotype of the Drosphila individuals exhibit circulating black spots but fail to melanize upon injury. By using these different phenotypes, it’s used as a control for the variables within the

C.elegans is clearly a very adaptable organism that has clear efficacy for investigations of the neurobiology of disease. C.elegans is a small (1mm), free-living, non-parasitic soil nematode, which can be safely used in the laboratory and is common around the world. The ease of manipulation and observation of the small, transparent nematode allows it to be cheaply cultivated in large numbers in the laboratory. C.elegans feeds on bacteria such

Drosophila melanogaster, often referred to as the fruit fly, is an interesting and dynamic insect that provides humanity with important information in the study of genetics. The biological community is extremely devoted to acquiring more information about the genetic process in order to improve the health and existence of humans. The fruit fly may seem like an insignificant specimen; however, it has a surprising number of parallels to the human genome. Humans have 46 chromosomes in which 23 are gametes involved in the reproduction process. Although, the fruit fly has only 4 chromosomes they behave very similarly to humans. This insight has led to new research and development that is continuously explored by scientists all over the globe.

Your response was nicely written. As the fruit flies are similar to humans that they carry a dopamine receptor in their brains, genetics are able to conduct research on chemicals and neurons in the brain. To be honest, after I first watched the video, I was confused and did not understand the research was doing. How can you teach a fly to learn? Also, how were they able to insert good genes inside the fly's brain and test for hyperactivity and distinguish abnormalities. These are small creatures, they were able to gather lots of information. There need to be new medications that reduce the side effects. For individuals with co-occurring disorders should be treated with medication that will help both disorders, not only one. Just like David

Drosophila melanogaster or fruit fly in general terms, was one of the earliest organisms that were used for genetics analysis by scientists. The reasons behind the use of this species are due to its small size, short generation time and the ability of females to lay a lot of eggs. Since Drosophila melanogaster has been studied in 1900, this have brought a large contribution to genetic studies and particularly used as model organisms in the Human Genome Project. In recent years, the whole genome of Drosophila melanogaster was sequenced and this bring innovations for scientists for deeper genetic analysis1. This helps another experiment which was conducted following the aforementioned study. The scientists studied the human disease-associated gene sequences in Drosophila melanogaster. They performed a systematic blast analysis of about 1000 human gene of diseases and associated mutant alleles against the complete genome sequence of Drosophila melanogaster. This analysis significantly helps promote interaction between individuals and Drosophila melanogaster research scientists and accelerate the understanding of the pathogenesis of human genetic diseases2. The previous example shows that Drosophila melanogaster is helpful in investigating on human genetic diseases, so an experiment was done by Drosophila melanogaster serves as a model of the well-known Parkinson’s disease3. By identifying the mutant gene, the model recapitulates the necessary features of human disorder and

The fruit fly, Drosophila melanogaster, has key characteristics that include a short life cycle of about 30 days at 29 °C, the production of large numbers of offspring, and minimal lab maintenance that make it an excellent model organism to conduct biological experiments [1]. D. melanogaster is a complex multi-cellular organism that shares closely related behavioral and developmental features, along with a highly conserved genome, with humans which allows researchers to study parallel developmental biology patterns while also bypassing the ethical limitations of experimenting on human patients [2]. One fruit fly behavior of particular interest is taste detection because these organism’s saccharide receptor binding mechanisms exemplify highly similar molecular features to those of humans, despite thousands of years of convergent evolution [3]. Observing fruit fly preference for different sugar substances via a behavioral food choice test can provide information regarding how highly evolved D. melanogaster sugar receptors have become by their extent to which they can distinguish the biochemical variations of different sugars, but more importantly reveal vital information regarding how their more complex human homologs operate.

Introduction: The study of Drosophila has brought great leaps of scientific research with it. As unlikely a candidate they are, studies of Drosophila melanogaster have done much in the way of proving theories, discovering genetically identifiable diseases and much more. Over the past three decades, research on this species has lead researchers to question the developmental processes that Drosophila experience (Bürglin 2016). The embryonic development of Drosophila serves as an important case study for developmental genetics, due to the analogous nature of their embryos cell differentiation. Although Drosophila’s development has very distinct variations when compared to that of vertebrates, there is a commonality between the embryonic development of the nervous system. The similarity between Drosophila and vertebrates gives reason to research the Homeobox genes in order to better understand a multitude of species with homologous development. In particular, the nervous development of Drosophila, could be used to investigate possible cures
