Lab 6 Drophisila Fly
Lab 6. Drosophila cross( start)
Melat Mebrahtu Lab Instructor: Professor Hicks Principles of Biology Lab II, Wednesday 1:00 am- 2:00 pm
Abstract The goal of this experiment was to examine the Drophisila fly cross for which the result was seen in two weeks .The Drosophila melanogaster has been a model organism that was experimented in the laboratory. It is a small fruit fly that feeds on and lives on spoiled fruit.
It is one of the most valuable organisms in genetics research and developmental biology. Drosophila’s are popularly used in studying traits because they are practical, small and have a short life cycle of about two weeks (Manning et al, 2006). We are demonstrating exactly how Drosophila melanogaster are used to identify mechanisms of transmission genetics in eukaryotes. F1 and F2 generations were obtained by performing simple parental crosses. This was done so that we could determine the mode of inheritance of the genetic trait of eye color . The chi square analysis data showed signs of our observed dating matching almost exactly to our expected data. Therefore we were able to accept our null hypothesis for all crosses.
Introduction
Drosophila melanogaster are very useful tool in the study of genetics. The gene studied is called apterous, with recessive allele producing very tiny wings and the dominant allele of the same gene leading to wild type wing structure. In this experiment we are hoping to determine phenotypic ratios and dominant vs. recessive traits by cross breeding two different types of Drosophila; such as wild type mutant (red eye) with white eye drosophila and wild type mutant (red eye) with sepia eye drosophila. . Drosophila are most commonly used organism in genetic labs because they have a short life span and genetically speaking they are a very simple organism. The mode of inheritance among traits is easy to figure out as well by applying simple Mendelian tools in this
