Drosophila melanogaster Population Genetics Introduction

Population genetics is a very important topic that has to deal with the structure of populations and how different factors and phenomena cause change in the populations genetic structure. Population genetics is a great way to study and determine if evolution occurs over time in a set population. Technically speaking, evolution

    In this experiment, Drosophila melanogaster, Drosophila virilis, as well as a marker strain (mutant strain of D. melanogaster) were used to examine the genetic variation. Electrophoresis followed by the staining of the proteins will cause the enzymes, aldehyde oxidase, alcohol dehydrogenase, and malate dehydrogenase, to become visible, appearing as a set of different banding patterns. The banding patterns will dependent on the molecular form of the enzyme, indicating the genetic variation that can exist between strains (Biology Department, 2014).…

    Flab Virtual Fly Lab Report

    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…

    Fruit Fly Lab Report

    This lab was the study of monohybrid as well as dihybrid crosses. A monohybrid cross is the study of a certain trait whereas a dihybrid cross is the study of the mating experiment between two organisms that are identically hybrid for two traits. ( Reference 1 ) This lab was done to determine the genetic mutations after each generation and to observe the ratios. As each generation of fruit flies came to existence, traits would either be different from each fly or certain traits would disappear from existence. The expected ratio for a monohybrid cross was 3:1 and 9:3:3:1 for the dihybrid cross. For the monohybrid cross, eye color was observed to be wildtype, dark red, or white eyed, which was x-linked. (Reference 2) As for the dihybrid cross, both wing shape as well as eye color was observed. The wings were either straight, wildtype, or shriveled, vestigial, depending on…

    In this lab a study of fruit fly genetics was done these creature are readily used for genetic studies .they are easy to maintain. And the females lay a lot off eggs which develop in about two weeks. Fruit fly’s have for distinct stages, the egg, larva, pupa and adult. the egg and larva stages last for eight days, the pupal stage last for six days and then the adult stage which last for many weeks this period of growth is called instars. In this lab a dihybrid cross was performed to get data results and to draw a conclusion to the hypothesis.…

    The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines, top jaw and bottom jaw, which were used to count how many incisors, canines, premolars, and molar teeth a species had. Species A, Odocoileus virginiaus (white-tailed deer), had a tooth formula of 0033/3133. On the top jaw, the deer had zero incisor and canine teeth but have three of both the premolars and molars. On the bottom jaw, the deer had three incisors, one canine, three premolars, and three molars. Species B, Canis latrans (coyote), had a tooth formula of 3142/3143. On the top jaw, the coyote had three incisors, one canine, four premolars, and two molars. On the bottom jaw, the coyote has three incisors, one canine, four premolars, and three molars. Both the deer and coyote skull were long and skinny towards the nose and mouth. The coyote skull had a much rounder nose than the deer. Species C, Homo sapiens (human), had a tooth formula of 2122/2122. On both the top and bottom jaws, there were two incisors, one canine, two premolars, and two molars. In comparison to the deer and coyote skull, the human was an outcast. The human skull was a short distance from the back of the skull to the front. The human skull was very different in bone structure and longer in height than the deer and coyote skulls.…

    How To Write A Pglo Lab Report

    In this particular situation we didn’t add enough PGLO into the DNA so ours didn’t glow. In the control lab a different outcomes was observed in each of the four plates. In the LB/amp/arabinose agarose plate containing the +pGLO sample, fluorescent green colonies developed. This is because the gene which codes for the fluorescent protein, GFP, is located near the beta lactamase gene on the pGLO plasmid, which protects bacteria from the antibiotic ampicillin. When the cell produced beta lactamase to deactivate ampicillin, the GFP gene was also transcribed, producing the fluorescent protein observed. In the LB/amp plate containing the +pGLO sample white, non florescent cells were observed. While these genes contained the pGLO plasmid and the GFP…

    I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid, repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip.…

    In vial one, a wild type hyper female Drosophila and wild type mellow male Drosophila were crossed respectively to determine the dominant behavioural phenotype. The first reciprocal cross was then carried out in vial two to define whether or not the behavioural phenotype is x-linked recessive. According to the results obtained from vial one, when the wild type hyper female and wild type mellow male was crossed, the resulting offspring’s phenotypes were all wild type hyper. This cross shows that the hyper behavioral phenotype can be considered dominant in comparison to mellow.…

    Recessive Alleles Lab Report

    The process of evolutionary change occurs at the level of the population. A population is a group of interbreeding individuals located in the same area and separated physically from other populations of the same species. The genotype of a population is called its gene pool and consists of all of the alleles present in the population members for all of the genes found in that species. Evolutionary change occurs when there is a measurable change in the population's genotype through time. Alleles are alternative versions of gene. An allele is said to be lethal if it directly causes death of the organism. A lethal recessive allele must be inherited from both parents to cause death; offspring must have two such (homozygous) recessive…

    Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was tested by having a chamber with quadrants that contain the culture, a hemacytometer, was used to carry out this experiment. After the data was collected from using the hemacytometer, the results of the difference between the two cultures was to be determined through a t-test. As the test was conducted, the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic in culture-A and culture-B does not affect the number of yielded yeast cells.…

    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…

    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,…
