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‚

AP Biology Lab Report Investigation 12: Fruit Fly Behavior Abstract: In the lab that was conducted‚ students were supposed to examine the tendencies of fruit flies‚ specifically Drosophila’s‚ to move toward or away from important stimuli that aide in their survival‚ also known as taxis. Another objective for this lab was to identify the patterns and relationships between environmental factors and a living organism. Students are supposed to use two bottles to allow the flies to choose

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

Drosophila melanogaster and how they respond to different stimuli and repellents‚ the research members decided to use mutant fruit flies‚ for this reason they lacked wings‚ making their manipulation simpler. In order to carry out this study it was necessary to first obtain an adequate number of flies to observe them throughout the weeks. The research members had the flies accompanied with larvae in stock vials‚ and later transferred these into a new vial containing a medium. After two weeks‚ when

Fruit Fly Lab Alycia Fletcher Biology IB HL March 25th 2010 Fruit Fly Lab Introduction Genes can either be sex-linked or autosomal. If a gene appears mostly in one sex chances are the gene is sex-linked and if it appears frequently in both sexes it is most likely autosomal. Using Drosophila melanogaster‚ also known as the fruit fly‚ we will determine whether the gene is sex-linked or autosomal. Drosophila melanogasters have a relatively short life span and are an excellent organism

Drosophila Melanogaster feed on fresh or decomposed fruit. We use a 1:1 ratio of instant medium to distilled water for the medium in culture vials that the flies will have to develop in. After making the medium‚ they have to be sprinkled with one or two grains of dry yeast to feed the flies. For the P1 and F1 cross‚ two culture vials V1 and V2 will be used just incase one vial doesn’t show as optimal breeding or medium as the other vial. When we isolate the flies and transfer them from one vial to the next

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

Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial
