Discover how certain traits are inherited in the Drosophila melanogaster fly.

The grading rubric doc. attached includes all of the criteria for the following sections:Abstract:The purpose of this lab is to discover how certain traits are inherited in the Drosophila melanogaster fly, and to understand the connection between presence or absence of a genetic trait in an individual and the ratio of those phenotypic traits in two generations. When we cross two individuals from the F2 generation in a dihybrid cross, we expect to find a phenotypic ratio of 9:3:3:1. (This phenotypic ratio where red eyes and normal wings were the dominant traits and black eyes and vestigial wings were the recessive traits.) With these results, in following with the laws of Mendelien genetic, this phenotypic ratio could only have been created from a 3:1 phenotype expressed dihybrid cross. Therefore, the unknown F1 generation was proven to have the 3:1 phenotypic ratio of dominant red-eyed normal winged phenotypes carrying the recessive alleles of black eyes and vestigial wings, seen as (RrWw x RrWw). The calculated chi-square of 10.48 > critical chi-square of 7.82. P-value > 0.05. Thus, we reject our null hypothesis because our calculated chi-square value (10.48) is less than the critical chi-square value (7.82) and our p-value is greater than 0.05.Intro:Must include a primary and secondary source, 4 sources total.Materials and Methods:(rough draft in list form- must be in paragraph form)• two separate culture tubes needed to be prepared with each tube specified for the specific crosses. To prepare the culture tubes for the flies to live and reproduce offspring,• a high carbohydrate and yeast media was created. In preparing the media,• one cup of fly media was added with one cup of water each culture tub and the solution was stirred and formed into a solid state.• One grain of yeast was then added to each tube, being careful not to add to much yeast to avoid overproduction of toxic carbon dioxide• the tube was then closed with a sponge stopper.Results:The results are attached in a Microsoft Word Document: \”Drosophila Class Data\” (must have a title underneath table)
