Fruit Flies Research Paper
Fruit Flies, also known as Drosophila melanogaster, are good insects to observe genetic testing. The fruit fly has obvious character traits which are easily seen when observing the fly body. There is also a vast variety of characteristics for each trait. The most common trait differences are the wings and eye color. The flies’ traits always follow Mendelian genetics and are easy to create pennant squares for. Plus the flies breed quickly, so the offspring will only take about two weeks to hatch and grow into adults. Fruit flies are also cooperate well to mate with any type. Genotype and phenotypes don’t matter when it comes to breeding. Also the flies produce hundreds of offspring, so you can easily tell the genotype of the generation prior.

    In addition to wild-type flies, 29 different mutations of the common fruit fly, Drosophila melanogaster, are included in FlyLab. The 29 mutations are actual known mutations in Drosophila. These mutations create phenotypic changes in bristle shape, body color, antennae shape, eye color, eye shape, wing size, wing shape, wing vein structure, and wing angle. For the purposes of the simulation, genetic inheritance in FlyLab follows Mendelian principles of complete dominance. Examples of incomplete dominance are not demonstrated with this simulation. A table of the mutant phenotypes available in FlyLab can be viewed by clicking on the Genetic Abbreviations tab which appears at the top of the FlyLab homepage. When you select a particular phenotype, you are not provided with any information about the dominance or recessiveness of each mutation. FlyLab will select a fly that is homozygous for the particular mutation that you choose, unless a mutation is lethal in the homozygous condition in which case the fly chosen will be heterozygous. Two of your challenges will be to determine the zygosity of each fly in your cross and to determine the effects of each allele by analyzing the offspring from your…

    To begin the lab, one must acquire a sample of flies to cross. These flies should be placed in a tube with an easily removable foam stopper. Use the flynap to knock out the fruit flies, and pour them out of the tube into a petri dish. Then place the petri dish on a stereomicroscope, and begin using a paintbrush to sort the flies by gender. Male flies have sex combs on their forelegs, and are usually smaller than the female flies. The females have pointed posteriors, do not have sex combs, and are usually larger.…

    The fruit fly or Drosophila melanogaster is ideal for classroom experiments. They are inexpensive, easy to nap, breed, as well as observe. It was very important to be able to tell the male and female flies apart from one another. The males are known to be usually smaller in size than the female flies and have bristles on their forelegs while the females lack this appearance. Also the males have a black or dark round end whereas the females have striped pointy ends. The Drosophila flies are small have dark red eyes and have a yellow-brown body. These flies are able to mutate within approximately ten to fourteen days at twenty-five degrees Celsius. The Drosophila has a…

    The species studied was the Drosophila melanogaster, or more commonly known as the fruit fly. This experiment was conducted to see how the relative fitness of two different phenotypes of the Drosophila melanogaster can affect evolution in the population of two different environments. The relative fitness of an organism is the ability of that organism to both survive and reproduce in its environment. A value of 1 is assigned to an individual is who is best suited for its environment, and all other…

    Bed bugs are one of the most dreaded parasites in any house. They suck blood from humans and as well act as disease vectors. They've also been a sign of an unkempt setting or home. Bed bug extermination is necessary at any time bed bugs are spotted in a home because it will be important to deal with the bed bug problem once it really is noticed than later. One from the reasons you need bed pester extermination immediately you spot the first is because bed bugs multiply extremely fast. Anytime they find somewhere to such blood, the next thing is reproduction and it will take just a short time before a whole home is full infested while using the bed bugs. In fact, because of the time you notice one cargo area bug, there usually are…

    Fruit flies have made a huge contribution towards knowledge about genetics, but for most people, they are just annoying insects that are attracted to their fruit. Their scientific name is Drosophila melanogaster, and to scientists, they have been a key to understand many principles of heredity including sex linked inheritance, epistasis, multiple alleles, and gene mapping. Fruit flies were the first organisms to be used for genetic analysis in 1910 by Thomas Hunt Morgan, and ever since, they have been used for genetic experiments (Ashburner).…

    You can be the mighty snake slithering along its own path to hunt for food or you can be in a pack of wolfs hunting with your brothers and sisters. This is the great battle between working as an individual or as a community. In William Golding’s book Lord of the Flies he expresses this battle of Individual vs. Community through his three major characters Piggy, Jack, and Ralph. Piggy is a boy who is always concerned about himself and his well being, Jack is a boy who only cares for himself and views hunting above all else, and Ralph who is a boy who thinks about the good of the group of boys and does his best for their well being.…

    As an undergraduate professor Lee attended UC Davis and graduated with BA Biology major, he then finished his Ph.D. in UC Berkeley. After graduation, he got a job in a lab.Professor Lee has been in the biological science department in UCSC since 2007. his current research includes using Drosophila fly to study genetic and development biology. I was impressed with Lee's techniques into studying Alzheimer's with the Drosophila fly(fruit fly). While I was reading the research paper, I had this unsettling question to why using precisely Drosophila fly to study Alzheimer's. However, during his lecture or presentation, I came to find out that the main reason he was using fruit flies was that they grow up fast their life spans approximates from…

    The X/Y sex chromosomes and the 2,3,4, autosomes. It is important to know the differences between the two adult sexes in order to record and collect the data accurately. The major sexual differences in Drosophila are apparent in the abdominal segment of the flies. In males, the last abdominal segment of the male is much larger and rounded than that in the female. Another indicator is the presence of sex combs present in males. Male flies has a small, densely packed bristles call sex comb on the outer joints of both forelegs. Females lack sex combs. Therefore, if one sees sex combs on a fly, it is certain that the fly is a male. Female fruit flies remain virgins for approximately six hours after hatching but will mate after the six hour window. It is important for the female flies to be virgin, so one knows which fly genotypes are…

    The purpose of this experiment was to determine the F1 genotype of fruit fly traits using the phenotypic ratio of the F2 generation and to express these results of the unknown cross through a Chi-square model and Mendelian genetics. After the experiment, it was found that the parents held a heterozygous genotype through using the Chi-square model, and that the observed and expected values fall within the Chi-squared value which also falls into the p-value. The Chi-squared value was 5.64, the degrees of freedom was 3 and the p-value was between .05 and .2, which supports the failing to reject the null hypothesis. The results also yielded the expected 9:3:3:1 ratio showing how different alleles combine and which ones are most prevalent. Using…

    These flies were observed in the lab by anaesthetizing them with triethylamine so they won’t fly away. They were then inserted in a vial with a foam stopper so then it was easier to observe them. A dissecting microscope was used to identify the color of their bodies, wing shape, sex characteristics, and any other body characteristics. We used female fruit flies who were virgins six hours after they came out of their cocoons and mated them with male fruit flies. This is how crosses were made while there were a few Genetic…
