    Drosophila melanogaster is a group of flies normally known as a common fruit fly, and widely used as an experimental organisms because they possess the ability to breed rapidly, survive in laboratory controlled conditions and have observable genetic mutations that enables different phenotypic differences. Dihybrid crosses shows lineages of two observable characteristics in a species, it was found by Gregor Mendel. This allowed scientists to conclude that genetic information can be inherited…

    Introduction Fruit fly Drosophila melanogaster that is used as a model to study genetics for more than a hundred years. Thomas Hunt Morgan, in the early 1900’s, used the heritable traits of a common species of fruit fly to develop our understanding of genetics. Morgan was the first to show through experiments that genes were located on chromosomes. He also found that certain fruit fly traits like eye color are found on the same chromosomes that also determine their sex. Fruit flies have several…

    Drosophila melanogaster is also known as the fruit fly. It “has played a central role in developmental biology during the twentieth century”. The fruit fly is considered a model organism for many reasons. Drosophila is low maintenance creatures that are easy to care for. Since they are such a small size, scientists are able to control numerous amounts of the Drosophila melanogaster at any given time. Drosophila reproduces many offspring and the offspring are created in a very fast fourteen-day…

    Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…

    Examining the inheritance patterns of genes of Drosophila melanogaster controlling some traits of eye color, body color, and wing shape by analyzing dihybrid crosses Csilla Szepe Introduction Our report will describe the experiment of three dihybrid crosses where we would like to understand if certain traits of Drosophila melanogaster follow the pattern of autosomal, unlinked inheritance. The subject of our experiment is the fruit fly because it has a short, two week long life-cycle that allows…

    The Drosophila melanogaster, also known as the fruit fly, was the primary research subject for Thomas Morgan. In 1910, Morgan used the fruit fly as an experiment to discover new mutations which could represent new species. Using the flies to research about heredity gave way to Gregor Mendel’s confirmation of his Chromosomal Theory of Inheritance which suggests that the chromosomes are the carriers of genetic information. The sex of the fly is important when culturing Drosophila and making…

    Introduction Drosophila melanogaster can be considered model organisms for the study of genetics. Some characteristics that contribute to this status are their quick lifecycles, large amount of offspring, and the presence of only four chromosomes. Drosophila melanogaster contain bristles on the thorax, head, legs, and abdomen. These bristles are used as a sensory mechanism, allowing fruit flies to detect their surroundings as they fly and walk around their environment (Yehuda, 2011). The rate…

    off of the phenotype of the offsprings. Background info: Fruit flies or Drosophila melanogaster work best in experiments because Drosophila melanogaster has 60% of genes that are mutated, amplified, or deleted in human diseases. Drosophila melanogaster also has a short lifespan which makes them best for quick experiments. They also mate and develop quickly, making it easier to study the offsprings. Drosophila melanogaster also have distinguishable characteristics that make telling the…

    Scientists have been using various organisms to perform experiments and do research to understand the various phenomenon that relates to human since doing experiments on human is against the law of human right. Drosophila melanogaster (fruit flies) is one of the model organism that can be used for various applications. In this experiment, the fruit flies were used to observe the basic genetic mechanism, leading to understanding the mode of inheritances of other organisms since they all share…

    The purpose of this experiment was to find out why Drosophila melanogaster is an important organism to understand eukaryotic genetics which was accomplished by first observing the sex of the flies and distinguishing between wild type and vestigial wing phenotypes. We also determined whether the allele that caused the vestigial wing phenotype is sex- linked or autosomal and either dominant or recessive from flies that were in the F1 generation. Our data collected by observing the sex of the F1…
