Introduction Drosophila melanogaster is a species of Fly (the taxonomic order Diptera) in the family Drosophilidae. The species is known generally as the common fruit fly or vinegar fly. Starting with Charles W. Woodworth’s proposal of the use of this species as a model organism‚ D. melanogaster continues to be widely used for biological research in studies of genetics‚ physiology‚ microbial pathogenesis and life history evolution. It is typically used because it is an animal species that is

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

organisms ate much smaller and easier to care for and observe. A major advantage to using these model organisms are their ability to rapidly develop off spring often times in much larger numbers than a human. Some organisms produce The fruit fly‚ drosophila melanogaster‚ is one of the smallest model organisms used to provide insight to the genetic development of humans. Development biologists won a Nobel Prize in 1995 for the genetic studies and later principles they discovered with fruit flies that

In other words‚ the researchers are trying to investigate the mechanisms of long-term memory consolidation in Drosophila through a courtship memory paradigm so as to determine whether

The Frequency of Mutations among Second Generation Drosophila melanogaster INTRODUCTION This experiment involved observing and comparing the relative frequencies of inherited dominant and recessive genes in a population using the common fruit fly Drosophila melanogaster. In this experiment‚ we demonstrate how dominant genes are selected over recessive genes (Mendel’s Law of Independent Assortment). Hypothesis: If we cross two heterozygous individuals‚ our observed offspring in the second

Christian Chou Mrs. McCarron 12/10/14 A.P Biology Drosophila melanogaster Genetics Introduction: The common fruit fly‚ scientifically named Drosophila melanogaster‚ is used by many in genetic studies. Because they can be easily cultured‚ have a relatively short generation time‚ and are prolific breeders‚ fruit flies are often very popular in genetic investigations. Furthermore‚ mutations and sex are easy to visualize among the fruit flies. Male fruit flies have a smaller abdomen than their female counterparts

Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination or justification

Abstract Drosophila Melanogaster is one of the best organisms to study when researching genetics; in particular sex linked genes on the X chromosome. The principle reason for this study was to determine what genes were transferred to the males from the females‚ as the males only inherit one X chromosome. Two experiments were conducted in which female and male flies were crossed. The first experiment was a cross between 5-trait females and wildtype males; the second experiment was a cross between

lab.Professor Lee has been in the biological science department in UCSC since 2007. his current research includes using Drosophila fly to study genetic and development biology. I was impressed with Lee’s techniques into studying Alzheimer’s with the Drosophila fly(fruit fly). While I was reading the research paper‚ I had this unsettling question to why using precisely Drosophila fly to study Alzheimer’s. However‚ during his lecture or presentation‚ I came to find out that the main reason he was

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest
