Kurt Worthmann April 21st, 2010 Biology 2: Concepts in Genetics Professor: Dr. Tacka Drosophila Lab Report The Drosophila Project Abstract Drosophila melanogaster is a small fruit fly that feeds on and lives around spoiled fruit. It is one of the most valuable organisms in genetics research...
changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment. A number of genes in Drosophila melanogaster are turned on when the animal is exposed to light. These include clock genes, whose products regulate the circadian clock. There are two key...
Introduction The Drosophila melanogaster, commonly known as the fruit fly, is a species of Diptera and is commonly used in biology because of its ease to study its chromosomes that resemble human chromosomes (Roberts, 1986). The fruit fly is an efficient genetic organism because they have a brief generation...
predict the cross results of Drosophila Melanogaster flies. Drosophila is commonly known as the “fruit fly”. This specimen is considered to be a “model organism” in biological research, and has been used for the good of science foe over a century (Hester, pg 5-1). Drosophila has been do widely used because...
scholar whenever the term genetics comes up. He carried out experiments using plants. The study also looks at Morgan also did experiments with the Drosophila and he came up with answers to questions, which he had on the eye color of these flies. INTRODUCTION Genetics is simply a branch of science...
different proteins to have the same relative mobility (Gómez, 1998). In this experiment, Drosophila melanogaster, Drosophila virilis, as well as a marker strain (mutant strain of D. melanogaster) were used to examine this relationship. After electrophoresis and a staining method take place, this...
determine if endomitosis takes place in the salivary glands of Drosophila virilis larvae. I hypothesize that endomitosis will be present in the salivary glands of the species Drosophila virilis larvae. The existence of several other Drosophila species which have endomitosis occur in their salivary glands...
regulation and evolution of a genetic switch controlling sexually dimorphic traits in drosophila, which is a new answer to Darwin’s puzzle on the gorgeous tail of male peacock. Keywords: Tail of peacock, genetic switch, drosophila When it comes to a peacock, it always occurs to us the image of its brilliant...
Determining two unknown mutations present in Drosophila melanogaster by designing and conducting crosses using FlyLab. By X Bio 2133 Section A6 Demonstrators: X March 21st, 2013 Department of Biology X Abstract: When one is given two unknown mutations, how does one discover what...
Eye Colour Genetics in Fruit Flies Lab Bio 1210 R02 In this Lab we studied how different variations in eye colour for fruit flies, Drosophila melanogaster, are produced. We looked at flies with brick red eyes, white eyes, and sepia eyes. To determine whether or not the gene was autosomal or sex-linked...
recessive that were passed on to offspring. Thomas Hunt Morgan – developed the field of genetics between 1905 and 1915 by working with Drosophila melanogaster (fruit flies). Showed that traits were linked to chromosomes, including sex-linked traits. Also the importance of mutations being passed...
research has focused upon elucidating the mechanisms of the P element insertion in Drosophila melanogaster. My dissertation research on molecular evolution and population genetics of transposable elements in natural Drosophila populations built upon this topic. This research and the projects that will stem...
identification of new alterations in cancer cells to be the guideline for their recognition from normal cells. The researchers use a certain fruit fly Drosophila melanogaster as a contribution to the comprehension of cancer in addition to discovery of new cancer related growths. In this case, rapid testing of under...

Results: Figure 1 depicts polytene chromosome of D. melanogaster consisting of two visible chromosomal tips, which join one another in a large unbanded...
invertebrate species are Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode worm. In the case of C. elegans, the worm's body is completely transparent and the precise lineage of all the organism's cells is known,[50] while studies in the fly D. melanogaster can use an amazing array...
which started out life as that egg, laying some more eggs of her own. This is the generation time, and can range from a little as two weeks in some Drosophila (Fruit flies); to seventeen years in some periodical cicadas and even longer in some dry-wood boring beetles. The most common lifecycles are univoltine...

In the article “male-specific lethal complex in Drosophila counteracts histone acetylation and does not mediate dosage compensation”, James A. Bircher researches the properties of MSL with a series of specific...
clustered not according to their function but to when they are expressed - for example, in a specific differentiation state. Expression profiles in Drosophila support the notion of gene clusters (Oliver et al., 2002; Spellman and Rubin, 2002). Under a wide variety of different experimental conditions, groups...
in parasite gene regulation. However, detailed mechanisms that control parasite gene expression are sparse. The bromodomain first reported in the Drosophila protein brahma represents an extensive family of evolutionarily conserved 110 aminoacids protein modules. Bromodomains are generally found in proteins...
offspring would you expect from a cross between the female Drosophila with red eyes (homozygous) and a yellow body and a male fruit fly with white eyes and a tan body. The alleles for eye color and for body color are on the X chromosome of Drosophila. Red eye color (w+) is dominant to white eye color (w)...

These vectors have already been used for cloning large DNA segments from the bithorax gene of Drosophila(for details consult Science; 16 June, 1989).
