Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Natural and Sexual Selection 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

throughout decaying food. The topic that is being examined is the Drosophila. When Drosophila is prepared for mating or hatching‚ they have a full lifecycle of about 20 days‚ thus are the models for relating sex-linked inheritance. Obviously it is not the breeding ways of the Drosophila that is being examined in this experiment‚ but the developing offspring‚ and their phenotypes. The phenotype is based on the wing shape and the eye color‚ which is resulted by grouping of genes

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

INTRODUCTION TO DROSOPHILA GENETICS DROSOPHILA CULTURE We will study basic principles of Mendelian inheritance with the use of the fruit fly‚ Drosophila melanogaster [the name means “black-bodied fruit-lover”]. Drosophila was one of the first organisms to be studied genetically: its small size‚ short life cycle (10 ~14 days at 25oC)‚ high reproductive rate (an adult female can lay 400-500 eggs in 10 days)‚ and ease of culture and genetic manipulation have made it perhaps the best understood animal

Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster‚ were crossed. Mutations were located on chromosome two and three respectively. The F1 generation‚ all Wrinkled and black‚ was inbred yielding and F2 generation. A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings

Phenotype of Drosophila melanogaster Eye Pigment Mariam Rahmanyar 100486882 T.A: Zahra Mortaji BIOL 2020 Results: Our TLC plate showed all colours expressed by the pteridine pigments for the wild-type Drosophila as expected (Figure 1). The sample A mutant which was a bright-red eye mutant also expressed the same pigments as our wild-type. Compared to the wild type‚ sample A pigment spots were lower intensity in colour under the UV light (Figure 2). Sample B was a brown-eye phenotype
