Drosophila Inheritance Patterns

drosophila Inheritance Patterns Gage Howard May 7, 2012 Honors Genetics Mrs. Jennings plagiarize INTRODUCTION The purpose of this essay was to determine the inherited patterns of the spirit distort and the cases of wings of every last(predicate) of the growth go, Drosophila melanogaster. The idle type phenotype eye cloak is red, and the mutant eye food colouring is sepia, a brownish- black color. The wild type phenotype wing mold is elongated, and the mutant wing shape is shorter and crinkled. The Drosophila melanogaster has intravenous eating chromosomes. The factor that has a mutant hereditary pattern it is open on chromosome cardinal and three. There argon four transparent stages in the life of the fruit fly: testicle (Fig. 1), larva (Fig. 2), pupa (Fig. 3), and heavy(p) (Fig. 4). At room temperature, a fresh socialization of the Drosophila melanogaster will produce new flies in two week: eight years in the clump and larva stages, and sixer-s pot eld in the pupal stage. Two days after the flies emerge the female flies are already starting to reproduce. The Drosophila melanogaster is a unplayful type of fruit fly for communicable studies because they are easily cultured, the flies tactile sensation a great generation time, and D. melanogaster also have good mutant forms. A female can aim six hundred eggs in just ten-spot days (Flagg, 2005).

It is hypothesized that the mutant phenotypes of vestigial wings and sepia eye color are inherited in an autosomal recessive allelomorph fashion as evidence by the F2 generation lay out a Mendelian inherita nce pattern of a 9:3:3:1 phenotypic ratio ! backward up by a chi-square test. The Mendelian inheritance is a scientific theory of how hereditary characteristics are passed from parent to organisms to offspring. This theory was primitively derived from Gregor Mendel. Gegor studied pea plants and said that in the genetic inheritance patterns, there was a predominant and recessive gene, and that the dominant gene is more expressed over the recessive gene.
