In order to begin, four vials of wild type Drosophila melanogaster, a set of vials, netting, sponge plugs, media, yeast, and FlyNap® were obtained from Carolina Biological Supply Company. Catalog numbers 172100 and 171905 were ordered which included the various fly vials and a basic fly care set. All experiments were conducted at Dr. Halloran’s school lab at 7400 San Jose Boulevard, Jacksonville, FL 32217. All usage of FlyNap® occurred under a ventilation hood in the lab. Before experimentation with flies began, vials were prepared with media. The first group, the control, had two vials and was labeled with pink tape. The media for these vials was prepared in a normal manner: media to water ratios of 1:1. A second group was prepared with a media to water ration of 1:1 and labeled with blue tape. The blue tape vials would have soy added to them later. The last group was labeled with white tape and had media to water to soy ratios of 1:1:0.5. Netting was then added to the vials for the flies to climb on. Finally, yeast was sprinkled on top of the media, as directed by the fly culturing kit. Flies from two vials of Drosophila melanogaster were anesthetized using FlyNap® and transferred onto a piece of construction paper. The anesthetized flies were then transferred into vials in approximately equal amounts by rolling the paper and letting them slide into the vials. Sponge topper plugs were then put into place and the flies were left to mate until a sufficient amount of pupa could be observed. After a sufficient amount of pupa and larva could be observed in all of the vials, the adult flies were anesthetized, and removed from the containers. Once removed, the sponge stoppers were put back into place. The removed adults were counted, recorded, and put in plastic ZipLock bags to be put into the lab refrigerator. A pinch of the powdered soy milk used in the white labeled vials was then

    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…

    This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments, one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism, and if evolution was occurring in the population. Two hypotheses were inferred, one for each environment. For the cage uninfluenced by a predator, we hypothesized that evolution would occur due to sexual selection, and that sexual selection would be in favor of the wild-type drosophila. For the cage containing the predator, we hypothesized that the vestigial flies would have a higher relative fitness due to natural selection. A ratio of wild-type to vestigial flies was determined, and was set up in each environment. 10 wild-type to 40 vestigial flies was chosen, giving a total of 50 flies for each environment. Each week the flies were fed, and every two weeks they were counted to represent a new generation. At the end of the 13 week experiment, the last generation of flies were counted and recorded in a data table. The results of the experiment show that evolution was occurring in both cages, and that wild type flies were dominant regardless of the environment.…

    Drosophila melanogaster better known as the fruit fly can be found near rotting fruits, vegetables, or anywhere where there is food that has rotted and or fermented. (Potter, 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days. Once the larva mature it will molt twice this period is called an instar. (Flagg, 1979) Instar means that the larva will shed a cuticle, mouth hooks, and spiracles and the period in which it goes through this growth phase of molting. D. melanogaster will go through 3 instars before reaching the pupa stage. (Flagg, 1979) The pupa stage will last for about 6 days after which the adult will eclose. During the pupa stage the pupa will darken and the eyes as well as the wings will appear visible through the casing.…

    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…

    Fruit Fly Lab Report

    Drosophila melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look, structurally. They are similar because both genders have a head, thorax, proboscis, antennae, eyes, and mouth parts. However, males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist of egg, larvae, metamorphosis, and then adult stages. During the egg stage of their life cycle, the eggs are sunk into the food until they become larvae that spend all of their time eating. After, the larvae go through two molting phases called instars,…

    Locomotor Behavior of Sarcophaga bullata in response to various light stimuli Introduction: The species Sarcophaga bullata (flesh fly) is from the Kingdom Animalia, Phylum Arthropoda and Class Insecta. Flesh flies live all over the world, generally in warm, moist climates. The flesh fly goes through the process of complete metamorphosis that consists of four stages: egg, larva (=maggot), pupa, to adult in about eight days. Through these different stages of metamorphosis the flesh fly is a parasite and a self-sustaining organism until it reaches full maturity. The job for the fly is then to disperse the species and reproduce. Flesh flies can be both pests and important aspects to human lives. They help in biological research and in criminal investigations but they also carry diseases that can harm humans.…
