The Frequency of Mutations among Second Generation Drosophila melanogaster INTRODUCTION This experiment involved observing and comparing the relative frequencies of inherited dominant and recessive genes in a population using the common fruit fly Drosophila melanogaster. In this experiment‚ we demonstrate how dominant genes are selected over recessive genes (Mendel’s Law of Independent Assortment). Hypothesis: If we cross two heterozygous individuals‚ our observed offspring in the second

Drosophila melanogaster are a species more commonly known to us as fruit flies. They are extremely important in biological research due to the fact that they make excellent model organisms for understanding genetics. Reasons behind their frequent use include; easily cultured in the lab‚ short generation time‚ and they can produce many offspring. In this lab report‚ we began with three different strains of Drosophila. Introduction The common form of Drosophila is known as the “wild type”‚ any fly

Introduction In most kitchens the small flies that are found are Drosophila Melanogaster also called fruit fly. They are often brought in by ripened tomatoes‚ grapes and other perishable items from the garden. Drosophila melanogaster is a little two winged insect about 3mm long two winged insect that belongs to the Diptera‚ the order of the flies. The drosophila egg is about half a millimeter long. Fertilization takes about one day the embryo to develop and hatch into a worm-like larva. The larva

The Drosophila melanogaster In this experiment‚ the species Drosophila melanogaster‚ the common fruit fly‚ was studied to examine the processes of natural selection and genetic drift in the laboratory. The fruit fly has a sex linked gene determining eye colour. Located on the X chromosome‚ a fruit fly can exhibit the phenotype white eye (homozygous recessive)‚ or red eyed wild-type (dominant). Males of the species are XY‚ and as such only carry one eye colour determining X chromosome. Females

Abstract Drosophila Melanogaster is one of the best organisms to study when researching genetics; in particular sex linked genes on the X chromosome. The principle reason for this study was to determine what genes were transferred to the males from the females‚ as the males only inherit one X chromosome. Two experiments were conducted in which female and male flies were crossed. The first experiment was a cross between 5-trait females and wildtype males; the second experiment was a cross between

Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster‚ were crossed. Mutations were located on chromosome two and three respectively. The F1 generation‚ all Wrinkled and black‚ was inbred yielding and F2 generation. A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings

Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination or justification

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

Christian Chou Mrs. McCarron 12/10/14 A.P Biology Drosophila melanogaster Genetics Introduction: The common fruit fly‚ scientifically named Drosophila melanogaster‚ is used by many in genetic studies. Because they can be easily cultured‚ have a relatively short generation time‚ and are prolific breeders‚ fruit flies are often very popular in genetic investigations. Furthermore‚ mutations and sex are easy to visualize among the fruit flies. Male fruit flies have a smaller abdomen than their female counterparts

Introduction Drosophila melanogaster is a species of Fly (the taxonomic order Diptera) in the family Drosophilidae. The species is known generally as the common fruit fly or vinegar fly. Starting with Charles W. Woodworth’s proposal of the use of this species as a model organism‚ D. melanogaster continues to be widely used for biological research in studies of genetics‚ physiology‚ microbial pathogenesis and life history evolution. It is typically used because it is an animal species that is
