    The English Peppered Moth and Natural Selection Lab By: Justin Pascual Partners: Nathan Magbitang, Rudy Keyes-Krysakowski, and Glenn Tipold Teacher: Ms. Coopman Date Performed: November 16, 2015 The English Peppered Moth and Natural Selection Lab Purpose The purpose of this lab is to determine how variation in a population can favour survival of a certain trait over multiple generations. Hypothesis It is believed that if there are more speckled moths remaining in the tray at the end…

    This article caught my eye in the first place because it reminded me of the apple magot fly simpatric speciation that we have studied and understood quite clearly in class. My first response to the whole simpatric and allopatric speciation was clear and it seemed to me that the apple maggot fly speciaton proved this concept. However simpatric speciation with the jays are considerably more unexplanitory, complicated, and as the article indicates, "weird". Katie Langin is the biologist in this…

    inheritance patterns of many generations in a short period of time. Different model organisms are utilized in many different ways. In the case of this experiment, a model organism must have a rapid rate of maturation and reproduction. The use of Drosophila (fruit fly) was chosen for its fast gestation period and ease of trait comparison between generations (Cartier and Stewart, 2000). This allows for scientists to gather multiple generations worth of data in a short period of time to see the…

    The main goal inathe experiment was to determine theainheritance pattern of aaparticular mutation. A asecondary goal in conductingathis lab was to study and comprehend mendelian genetics. In this experiment, Drosophilaamelanogaster, commonlyaknown as fruit flies, were used to studyaand understand the principles of mendelianagenetics. D. melanogasterawas also used as a model to identifyathe patterns of inheritance of certainamutant traits in fruit flies. Mendel’salaw ofasegregation is important…

    Evolution is defined as a change in allele frequencies from one generation to another generation with time. To test the evolution theory, Drosophila was chosen as a great experiment organism because of its short life cycle, rapid development, its small size and the large amount of breeding data can be produced. There are two types of allele of Drosophila observed which are ebony allele and wild-type allele. While wild type allele is dominant and easily found in nature, the ebony type is a…

    Introduction: Drosophila melanogaster, which commonly is known as fruit fly, has been used in genetic study for centuries. They tend to give birth to a large amount of offspring while their life cycles and generations are short. Their genes can be mutated easily by radiation or mutagens in food. They have four large chromosomes with approximately fourteen thousands genes. As expected, human have several times more gene than D. melanogaster, however, we have almost the same number of gene…

    Introduction Drosophila melanogaster, commonly known as fruit fly or vinigar fly coming under the family Drosophilidae. The normal life span of the flies are generally 30 – 60 days and it may vary depend upon the external conditions. These flies are sexually dimorphic. The female flies are comparatively bigger than the male flies. The males flies and females fly can be easily distinguish with size difference and the colour pattern. The male flies have a dark band on the abdomen. The presence…

    nuisance when I hear the cacophonous drone of its wings and hunt its relatives who buzz too quickly across my vision to properly see. But in a lab, we’re the closest of friends. When in lab, the fruit fly isn’t the fruit fly, but the Drosophila melanogaster. Drosophila melanogaster is an unassuming, unappealing little creature. Their bodies are so normal it is almost boring: beady red eyes and long, translucent wings. The females have a pointed, striped abdomen, while the males have a rounded…

    experiment is concentrated on two types of Drosophila melanogaster flies: wildtype and the vestigial. The vestigial flies have small, shriveled wings caused by the mutation on the second chromosome. This mutation is recessive, so in order for the flies to display shriveled wings they must carry the mutation on both copies of the chromosome (Franklin, 2014). The reason why our experiment is focused on the wings of these flies is because Drosophila melanogaster males perform mating dances that…
