Drosophila melanogaster

The studies in Drosophila melanogaster have helped scientists to have better understand about genetic and scientifically discover the variety of human diseases from mutations. After observing under 50X magnification, the differences between the female and male unknown mutants 651 are that the shape of male’s pseudopupils are larger than female’s and the volume of bristles and hairs on male’s notum are greater than female. In addition, the larva of wild type is a little larger in length and width

Abstract Genetic variation in Drosophila melanogaster and many other species is dependent upon recombination events during Meiosis I. In previous experiments, age of females, behavioral stress, and fluctuations in temperature has had an effect on the frequency of recombination. The purpose of this experiment was to observe the effects of changing incubation temperature on recombination frequency by conducting crosses in different thermal conditions of 25°C, the control, and 30°C, the experimental

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

Genetic Crosses In Drosophila melanogaster Edison Nurcellari, Norma Sutton, Lisa Brown Abstract: The purpose of this experiment is to see how characteristics such as ( phenotypes) are transmitted from parents to offsprings by using true breeding stocks. While doing more than two test crosses from the parent the alleles are re-shuffle so the offsprings get different variations sets of allele then the parents. This process is known as genetic recombination which occurs during meiosis

Autosomal Recessive Traits in Drosophila melanogaster Introduction Drosophila has been used in many experiments over the years, and hundreds of mutations have been studied. Drosophila was used in the chromosome theory of inheritance performed by geneticist Thomas Hunt Morgan. The chromosome theory of inheritance shows that genes on a chromosome are inherited together. The traits in Drosophila melanogaster was observed because they are inexpensive and easy to work with. Millions can fit in a single

Documenting independent assortment and genetic linkage In Drosophila melanogaster Marina Gayed BIOL 3251-004 Mr. Matthew Fuller 11 October 2017 Lab Partners Abdelrahman Sedik Aida Abdalla Eriny Saad According to Gregor Mendel, he came across two different inheritances laws found in genes: segregation and independent assortment. Mendel’s Law of Segregation states that each individual gene carries two alleles that segregate each allele into a different gamete during the phase of meiosis

Introduction Genes are unique segments of DNA and in this laboratory experiment, the Actin gene of Drosophila melanogaster will be extracted and amplified with various laboratory processes including PCR, ligation, and transformation. Also, the gene that was extracted will be confirmed and sequenced with the process of cycle sequencing and with the help of NCBI database. The DNA that is first extracted will be referred to as “genomic DNA” because it was extracted directly from the fruit fly, but

Upon analyzing the mutant Drosophila melanogaster and comparing it to its wild type counterpart, it was determined that the allele of the mutant gene phenotypically alters eye color. There are no other physical differences concerning bristles, wing shape, body color, wing venation, nor eye shape. Wild type male and female D. melanogaster have vibrant orange eyes with the addition of a black, pseudo-pupil in the center (Figure 1. C and D). Their eye color appears to darken with age. Male and female

Drosophila Melanogaster is a fruit fly that is commonly used for genetic studies (reference 2). It is an excellent organism for genetic studies because it is small, inexpensive and easy to culture. It occupies little space, and requires simple food (reference 3). Also, it completes its life cycle in about 10-14 days at 25ºC and It produces large numbers of offspring (reference 3).Moreover, it has abundance of heredity variations, and it has a small number of chromosomes which are easily
