Drosophila melanogaster‚ more commonly known as the fruit fly‚ is commonly used as a model organism in genetic research. Using D. melanogaster has a multitude of practical advantages for researchers. These include a fast reproduction cycle of approximately 30 days‚ small physical size‚ cost-effective culture and growth in large quantities‚ and a small genome size of 4 pairs of chromosomes. A basic understanding of the anatomy and genetics of D. melanogaster is necessary before preforming genetics

Effects of Organic Food on Drosophila Melanogaster A new study has shown that fruit flies that lived on organic foods tended to be healthier than those that lived on conventional foods. The two things that researchers based their conclusions for health on were fertility and longevity. These two things are two important aspects to a fly’s life. On both of these tests‚ the flies that were fed organic food performed better than the flies that were fed conventional food. They survived for a longer

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L

be expressed in the phenotype if it is present. In a cross pollination experiment between yellow and green pea plants exclusively‚ the first generation offspring was always yellow. However‚ the second generation consistently produced offspring in a ration of 3:1. This ration continued though out further generations. This means the first generation was homozygous but the second became heterozygous. These laws and experiments underline monohybrid inheritance because they form the basis of the punnett

APPENDIX 5 - Writing Reports Report 1: Drosophila F1 Generation Report General Notes: This report is very much a practice run to get you used to this style of report writing‚ rather than simply filling in lab sheets. It should not be a long report (no longer than these notes‚ in fact). Scientific writing is not like writing essays in other genre. In many ways it is easier! There are three important rules to scientific writing and if you adhere to these‚ the rest is quite easy: 1. Sentences

Biology 301 12/3/2012 The Effects of Relative Fitness of Drosophila Melanogaster on Evolution Abstract This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments‚ one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism

Ethanol sensitivity in Drosophila melanogaster based on genotype Alexa Shumate Department of Biology Randolph-Macon College Ashland‚ Virginia Introduction With a better understanding of the genes and behaviors associated with ethanol sensitivity‚ there will be new treatments available for alcohol dependence. The main problem in determining what causes dependence to alcohol is whether it is an environmental factor or if it is the genes associated with ethanol
