melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look‚ structurally. They are similar because both genders have a head‚ thorax‚ proboscis‚ antennae‚ eyes‚ and mouth parts. However‚ males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist of egg‚ larvae‚ metamorphosis

Biology 2/2/15 Block 1 Introduction and Background Drosophila melanogaster or more commonly referred to as “fruit flies” have been used for genetic research for over 100 years. During his time at Harvard university‚ Charles W. Woodworth is credited with being the first to suggest fruit flies be used for genetic research. A century later‚ fruit flies are the most widely used eukaryotic organism for genetic research (Drosophila). Their ease of use and rapid rate of reproduction has

Lab 6. Drosophila cross( start) Melat Mebrahtu Lab Instructor: Professor Hicks Principles of Biology Lab II‚ Wednesday 1:00 am- 2:00 pm Abstract The goal of this experiment was to examine the Drophisila fly cross for which the result was seen in two weeks .The Drosophila melanogaster has been a model organism that was experimented in the laboratory. It is a small fruit fly that feeds on and lives on spoiled fruit. It is one of the most valuable organisms in genetics

melanogaster commonly known as the fruit fly is considered a model organism in the field of genetics because of its short life cycle of about 10 weeks and the ability of the fly to produce a relatively large number of offspring at 50-70 eggs per day upon female maturity. The physical size of the male and female Drosophila is approximately 2.5 to 3 mm respectively Drosophila allowing for minimal storage space in a laboratory setting. The intricate nervous system of the fruit fly has made them very vital to genetic

Fruit Fly Genetics Lab Kelly Hernandez 5/31/14 Drosophila melanogaster is a small‚ common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination‚ which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain‚

begin the lab‚ he/she must make a prediction about what gene the trait one are analyzing is on. The trait can either be sex-linked‚ or autosomal. To begin the lab‚ one must acquire a sample of flies to cross. These flies should be placed in a tube with an easily removable foam stopper. Use the flynap to knock out the fruit flies‚ and pour them out of the tube into a petri dish. Then place the petri dish on a stereomicroscope‚ and begin using a paintbrush to sort the flies by gender. Male flies have sex

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

The Dumpy Sepia X Wild Type Dihybrid cross using Drosophila Melanogaster. Abstract An experiment was performed on the fruit fly (Drosophila Melanogaster) in order to investigate Gregor Mendel’s postulates and determine if his laws were in fact correct. This was done by crossing Virgin Wild type females with Dumpy sepia males‚ and then inter-crossing their progeny (the first filial generation) in order to produce the second filial generation which was then studied. The results of this were designed

FRUIT FLY PURPOSE: The purpose of this lab is to determine what genetics are dominant and which one is recession in the fruit fly and to see what genetics are past down from generation to generation.
