Drosophila melanogaster

Drosophila Melanogaster (common fruit fly) is widely used to understand the complex processes involved in genetics and development. The nervous system of Drosophila and vertebrates consists of neurons and glial cells. Glial cells are the most abundant cell type in the nervous system. Glial cells are cells in the central and peripheral nervous system that provide support and protection for neurons, form myelin and provide insulation. In vertebrates, the glial cell subtypes are: astrocytes, oligodendrocytes, microglia, and Schwann cells. In Drosophila, the glial cells subtypes function similarly and are known as cortex glia, neuropil glia, surface glia, and peripheral glia. In our lab, we will focus on neuropil glia which functions similarly to oligodendrocytes (produces myelin in CNS).…

Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

Qualitative Determination of an Unknown Genotype of Drosophila melanogaster Through the Creation of Various Fly Cross Prepared for T.A. Lillian Doerfler PCB 3063L-013 By Hana Soueidan Partners: Kristina Hernandez Brendan Meyer Andrew Vasquez Feb. 24, 2017 University of South Florida Materials and Methods Culture Vial Preparation and Drosophila melanogaster Maintenance Vials for maintaining D. melanogaster were prepared by packing dry fly food, mixed with equal parts of deionized water…

ABSTRACT Often within the field of genetics, researchers must use forward genetics to identify the genetic basis of a mutation. This work employed Drosophila Melanogaster with an unknown mutant gene with small narrow eyes compare to the wild type. (Figure11) We set up experiments to discern the inheritance pattern as well as the specific locus and chromosome of the unknown (un) gene. The first step was to find out if the un gene was recessive or dominant. To discover the inheritance pattern of…

The simple but revolutionary organism Drosophila melanogaster has intricate properties that are studied to find its relations with human genes. Not only is D. melanogaster a model organism for its rapid growth, inexpensive culturing, and easy modifications, the Drosophila can provide more in-depth scientific analysis that can solve human diseases. The model organism D. melanogaster is studied to find ground-breaking research in neurology, sleep, cancer, and drug discovery. The multivariable…

Introduction: The Drosophila melanogaster, otherwise known as the common fruit fly has been a useful organism to the field of genetics. It has a relatively short generation time of approximately 10 days at 25 degrees Celsius, and yields a large amount of offspring. This results in large amounts of data over a short time period. In this lab, the purpose was to demonstrate how the Drosophila melanogaster is used in the field of genetics to study the inheritance of traits throughout the F1 and F2…

Lillian M. Cosentino University of North Carolina Wilmington Rachel Hanson BIOL 335-204 7 October 2015 Determining mode of inheritance for eyeless mutation in Drosophila melanogaster Abstract: The purpose of this experiment is to determine the mode of inheritance for the eyeless mutation in Drosophila melanogaster, whether it be autosomal or sex-linked. I hypothesized that the eyeless mutation in Drosophila melanogaster is inherited…

gene in Drosophila melanogaster Introduction The Drosophila melanogaster is considered a pest by most, but it has been used a model organism to study genetics for over a century. Shortly after Gregor Mendel had experimented with pea plants, Thomas Hunt Morgan experimented with fruit flies to better understand heredity and genetics as a whole. Many generations can be studied in short amount of time, with live cycles averaging 12 days at about 25 °C. The size of the flies are small and easily…

In addition to being small and easy to…

Drosophila melanogaster: Inheritance Pattern Experiment Kaitlyn Grifka Saginaw Valley State University Abstract The purpose of this experiment was to study a population of Drosophila melanogaster, or more commonly known as the fruit fly. Our main goal was to determine if our flies displayed an autosomal recessive inheritance pattern or an X-linked recessive pattern based on the two different mutations that were existing in the population. Those mutations include having vestigial wings, sepia…
