The Drosophila melanogaster is used to model diseases such as Cancer, Diabetes, and Huntington’s Disease. By studying the changes in how the proteins interact, the origin of such disease can be found providing a deeper understanding of how to cure these fatal ailments. Since Drosophila melanogaster is 70% similar to the human genome mutation in humans can easily be replicated in the flies. Due to their short lifespan, the Drosophila melanogaster allow for the progression of the mutations to occur rapidly and allow tracing of the mutation into subsequent generations. Drosophila melanogaster generally has a phenotypic change associated with mutated genes that control the coding of certain proteins. A mutation in the cinnabar gene, which causes the ocelli to become colorless and the eyes to become a bright red color, was originally discovered by Roy Clausen, a professor at the University of California in 1918. The cinnabar gene is a protein coder gene which controls how theShow MoreRelatedThe Common Fruit Fly By Gregor Mendel1404 Words   |  6 Pagesbe studied on a multitude of organisms, some more than others. Drosophila melanogaster or the common fruit fly has been studied in depth for its great advantages, such as size, reproduction rate, ease of care and inexpensive room and board. In this experiment we tested to see what the offspring of an unknown cross of an F1 generation would produce. After observing the F2 generation and recording the data we found some of the Drosophila showed mutations, two in particular. The mutations were the apterusRead MoreA Study On Drosophila Melanogaster1742 Words   |  7 Pages Abstract Drosophila melanogaster was used for this study for their fast reproduction cycles, fast regenerations, large amounts of offspring for each generation and their capability of living in a small limited space. The dominant or recessive genotype could be determining by the used of Mendelian genetic ratios for wild-type to mutant’s genes. The mutation that this study focuses on is the defects of the phenotypes in the common fruit fly, example; wing shape, wing sizes, body color and whatRead MoreExamination Of Cell Division And Dna Replication956 Words   |  4 Pagestraits that hinder survival, otherwise known as natural selection. Drosophila melanogaster, more commonly known as the fruit fly, has been used for over 100 years to research genetics. All organisms have a common genetic systems. Therefore, studying sequences in fruit flies helps with the understanding of these sequences in other eukaryotes, namely humans. There are many reasons for using this particular organism. Originally, the fruit fly was probably chosen for its simplicity. They are small and canRead MoreGenetic Mutations And Sex Linked Crosses That Each Generation Of The Fruit Fly Can Make1152 Words   |  5 Pages Drosophila melanogaster is an important model organism in biological research and has been prevalent for over one hundred years. Fruit flies are used by researchers because they having many qualities that make them favorable in research including their genetics, size, and reproductive capacity. The goal of the experiment is to test the different genetic mutations and sex linked crosses that each generation of the fruit fly can make .

An experiment done on the common fruit fly shows how the dominant and recessive traits appear in the generation tested. The data collected and found by using a chi-square and Punnett square that allowed a hypothesis to be made and the decision to be accepted or rejected. Drosophila Melanogaster, the common fruit fly is an essential organism to use for genetic research because of its simple living requirements and choice of diet. The fly can also be easily sedated and obtains manyRead MoreDrosophila Melanogaster Lab Experiment2429 Words   |  10 PagesInvestigation | May 28 2013 | Drosophila melanogaster lab experiment Question:  How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila, then the determination or justificationRead MoreNatural and Sexual Selection of Vestigial and Wild Type Drosophila Melanogaster2428 Words   |  10 PagesSelection of Vestigial and Wild Type Drosophila melanogaster Abstract In this experiment, vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection.   The wild type has a relative fitness of 1 since it has fully functional wings.   Vestigial Winged flies are not as sexually appealing sinceRead MoreDrosophila Melanogaster : A Model Organism Within Genetics Research Essay2081 Words   |  9 PagesDrosophila melanogaster is a species of fruit fly, used as a model organism in genetics research. We used this species to test the pattern of inheritance of two traits; eye color and wing type. With Mendelian Genetics, we assume genes are not linked. Thus, our hypothesis is that the genes are not linked. We ran two crosses, one with a wild type female and mutant male, and one with a mutant female and wild type male. We then proceeded to look at th e two generations following this original cross; theRead MoreThree Point Test Cross and Gene Mapping in Drosophila Melanogaster560 Words   |  2 PagesThree Point Test Cross and Gene Mapping in Drosophila Melanogaster Many traits incorporated into the design of the Drosophila, commonly known as the fruit fly, make it an optimal specimen for scientific research.
