Introduction The purpose of the experiment that has been conducted is to breed Drosophila melanogaster for specific traits. We used a dihybrid cross where the traits were sex linked. The cross is considered dihybrid due to the fact that we are crossing two different traits. The traits used for this dihybrid cross experiment are white eyes (w) and vestigial wings (vg). The white eyes are the sex linked trait. These traits were taken and crossed with wild type D. melanogaster. The experiment

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

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

mammals is also present in other animals‚ specifically in Drosophila‚ and if so‚ to try to understand the neural pathways that are involved in the process of memory acquisition and consolidation‚ and understanding how the information acquired from the learning experience is stored and protected during the period of delay. 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

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

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

Drosophila melanogaster are a species more commonly known to us as fruit flies. They are extremely important in biological research due to the fact that they make excellent model organisms for understanding genetics. Reasons behind their frequent use include; easily cultured in the lab‚ short generation time‚ and they can produce many offspring. In this lab report‚ we began with three different strains of Drosophila. Introduction The common form of Drosophila is known as the “wild type”‚ any fly

The fruit fly Drosophila melanogaster are an excellent specimen for research in genetics. Many reasons are that they have a rapid reproduction rate‚ easy to care compared other animals and less expensive. Researchers have determined the nucleotide sequence of nearly the entire 120 megabase euchromatic portion of the Drosophila genome (Cite). Drosophila has a simple genetic arrangement of only four chromosomes which contains three autosomes and one sex chromosome according to(--) and because of this
