Drosophila

Traits are inherited in a variety of ways ranging from dominate or recessive and sex-linked or autosomal. Using different model organism, scientists are able to study inheritance patterns of many generations in a short period of time. Different model organisms are utilized in many different ways. In the case of this experiment, a model organism must have a rapid rate of maturation and reproduction. The use of Drosophila (fruit fly) was chosen for its fast gestation period and ease of trait comparison between generations (Cartier and Stewart, 2000). This allows for scientists to gather multiple generations worth of data in a short period of time to see the inheritance pattern. This will allow them to distinguish if the trait was a dominate or…

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…

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…

The Drosophila melanogaster, also known as the fruit fly, was the primary research subject for Thomas Morgan. In 1910, Morgan used the fruit fly as an experiment to discover new mutations which could represent new species. Using the flies to research about heredity gave way to Gregor Mendel’s confirmation of his Chromosomal Theory of Inheritance which suggests that the chromosomes are the carriers of genetic information. The sex of the fly is important when culturing Drosophila and making…

The Spotted Wing Drosophila, (SWD) scientifically known as Drosophila suzukii Matsumura, is not your average fruit fly. Going by multiple aliases such as the cherry fruit fly or the cherry vinegar fly, the SWD has made a rather unattractive name for itself. The Spotted Wing Drosophila’s Taxonomic Tree is as follows: Domain: Eukaryota, Kingdom: Metazoa, Phylum: Arthropoda, Subphylum: Uniramia, Class: Insect, Order: Diptera, Family: Drosophilidae, Genus: Drosophila, and Specieis: Drosophila…

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,…

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…

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…

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 Spotted Wing Drosophila fly (SWD) is a quickly spreading across the United States of America. As SWD numbers get larger the number of fruit crops gets smaller. Aijun Zhang, a chemist working with the Agriculture Research Service, Invasive Insect Biocontrol, and the Behavior Laboratory in Beltsville Maryland, has found a solution to the SWD problem, Methyl benzoate. Methyl benzoate is emitted by snapdragons and petunias, to attract bees. SWD, unlike bees, is repelled from Methyl benzoate,…
