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

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 which

ABSTRAT PAGE We had to pick a lab to do and we had four choices. We could pick one on the how genes are pasted down from generation to generation. 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. INTERODUCTUON: Mendel’s pea did and experiment that was

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

Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping.

Genetics With Drosophila Flies Josh Derrall Lab Group: Dana Gilkes James Lupo Olivia Giannola December 4‚ 2012 Prof. Hunter Introduction Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However‚ since Mendels discoveries
