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…

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…

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…

Title : Drosophila melanogaster Sexual Inheritance Patterns Introduction: This experiment determines sexual inheritance patterns amongst drosophila melanogaster. The model species drosophila melanogaster was used to study the passing of genes from one generation to the next. These fruit flies are good model species because the birth and generation process happens very quickly comparatively. One generation of a fruit fly lasts approximately 10-14 days. Several different traits were chosen to…

Drosophila melanogaster the concept to understanding genetic inheritances from Parental to Offspring Lab Three: Genetic Experiments with Drosophila Arizona State University Kira James Professor Hoffman LSC 348: Fundamental of Genetics Lab Monday 27 October 2014 Abstract Drosophila melanogaster is a small, common fly found near upripe and rotted fruit. It is one of the most valuable organisms in genetics research since they are practical, small and have a short life cycle of about two weeks…

The Drosophila melanogaster has been a novel model organism for researchers for over a century studying various species at a molecular level. Because Drosophila has a short life cycle and easy to manipulate advocates Drosophila as a good model organism. The insight into molecular mechanisms in studying this species is why it has been used for such a long period. This organism is easy to manipulate to observe the changes over time, and because of this the variability among these species allows…
