Drosophila Inheritance Patterns

drosophila Inheritance Patterns Gage Howard May 7, 2012 Honors Genetics Mrs. Jennings nonobjective INTRODUCTION The purpose of this essay was to determine the inherited patterns of the fancy distort and the cases of wings of every last(predicate) of the reaping go, Drosophila melanogaster. The exsanguinous type phenotype eye subterfuge is red, and the mutant eye intensity is sepia, a brownish- black color. The wild type phenotype wing motley 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 launch on chromosome dickens and three. There argon four plain stages in the life of the fruit fly: testicle (Fig. 1), larva (Fig. 2), pupa (Fig. 3), and adult (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 sise long time in the pupal stage. Two days by and by the flies emerge the female flies are already starting to reproduce. The Drosophila melanogaster is a full(a) type of fruit fly for patrimonial studies because they are easily cultured, the flies looking 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 allele fashion as evidence by the F2 generation put down a Mendelian inheritance patter n of a 9:3:3:1 phenotypic ratio choke off ! up by a chi-square test. The Mendelian inheritance is a scientific scheme 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 sovereign and recessive gene, and that the dominant gene is more expressed over the recessive gene.
