In order to begin the experiment‚ culture vials for the flies were created. After wearing the proper safety gear‚ including but not limited to gloves and a lab coat‚ the fly food source was made using roughly an equal amount of distilled water and fly food. These were mixed until it had a mashed potato-like consistency. It mustn’t be too liquid-like as it will kill the flies; and should be solid enough to not slide around the vial. After obtaining and labelling a new vial‚ the food mash was placed

Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

POPULATION GENETICS (FRUITFLY) NAME: Christopher N. Anah CLASS: BIOL 2108L INSTRUCTOR: DR. JAMES BATTEY OVERVIEW: In this lab the Drosophila melanogaster fly species were used to do genetic test crosses. Students were taught how to manipulate phenotypes‚ collect data from F1 through the F4 generations‚ and analyze the results.INTRODUCTION: The basic principles of genetics are very often shared by a vast array of organisms. For that reason‚ it is usually only necessary to study the genetic

The scientists‚ Seema Sisodia‚ Puja Verma and Bashisth Narayan Sing explain there research in “The Effect of Diet Quality and Associated Metabolic Changes in Adult Stress Response and Life-History Traits in Drosophila Ananassae” The D. ananassae used in the experiment are flies collected from fruit and vegetable india in October 2010. The purpose of the study was to observe the role of diet during stress response at cellular and metabolic levels in fruit flies. Before the

Kayla Berezne Mrs. Cohen Honors Biology 24 March 2013 Genetic Predictions in the Fruit Fly The Drosophila melanogaster is a fruit fly with a very short life cycle. They can be winged or wingless‚ and have red eyes or white eyes. The different options are called alleles. Alleles are the variants of a specific gene‚ and one is received from each parent on each chromosome. (“What Are Dominant and Recessive?”). It was chosen to use winged females and wingless males to predict the offspring in this

Materials and methods 1. Raw materials Full ripe cactus Opuntia dillenii fruits were harvested from the orchard of Faculty of Agriculture‚ Suez Canal University‚ Ismailia Governorate‚ Egypt during December 2014. Fruits were washed and glochides and the two distal parts (top and bottom parts) were removed. The fruits were mashed in a mixer by mixing for 15 s. After that‚ the seeds were separated‚ washed and dried by hot air in a convective dryer (WT-binder‚ Type F115‚ Germany) at 50 ºC‚ air velocity

Cassie Browne Anthony Lulgjuraj Fly Lab Report Friday 9:30am Mutation #620 X Mutation #644 1) The vial labeled Mutation #620 contained female flies that displayed a mutation in eye color. This mutation causes a change in eye pigment from wild type (bright red) to a dark‚ reddish brown. The males possessed mutation #644. It is a mutation in wing morphology that reduces wing size. A controlled cross was conducted between these two true-breeding mutant flies. Their progeny (F1) being heterozygous for

occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic. One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials
