1- I would like from you to write a report containing abstract, introduction, results, discussion, conclusion and references.
2- It is VERY VERY important to read the uploaded files.
3- When it comes to working out the expected numbers for your Chi-square test, use the total number of flies counted for the relevant categories, and from that, work out what number would be expected if the flies came in the proportions stated in your null hypothesis.
The Chi-square test only needs to be done on males OR females, not on both sexes. The number of relevant categories are different for males and females, so this means that your degrees of freedom will be different when looking up the Chi-square value in the table. As females had some categories with a zero expectation, we shall simply ignore them for the test and only work with TWO expected categories (thus ONE degree of freedom), while for the males, we have four expected categories and thus THREE degrees of freedom.5- i want you just to write about MALE GENETICS because in this report you have to choose one gander..

Abstract: The Experiment aimed at establishing a genetic research hypothesis regarding two 
traits of Drosophila melanogaster viz. Eye Color and Wing type. The hypothesis states that 
expected phenotypic ratio of males of F2 generation on crossing a White male and Vestigial 
female is 3:3:1:1.A Chi-square test was conducted to test if the observed ratio in the experiment 
was same as expected ratio. Chi-square test gives calculated value of 15.11 and p value 
corresponding to it was less than 0.01 thus we rejected null hypothesis and research hypothesis 
was not true in this case. 
 Introduction:  Genes of every living organism defines their traits and the study of this behavior 
of genes and reasons behinds these is one of the core and focus topics of study of genetics. To 
understand and check the working behind those genes we need some organism which is available 
in masses and shows traits clearly.  Drosophila melanogaster or fruit fly has a small size and 
short life span; these are required conditions which makes it worthwhile to raise the large 
number of these flies for experimental purposes. One of the other important features which 
makes Drosophila an important experimental species is that it has a 1/20 times genome the size 
of typical genome of a mammal. In the present practical we are checking if the phenotypic ratio 
of male Drosophila in F2 generation obtained in our experiments is close to as expected using a 
chi square test. 
Results: 
F2 Generation obtained from an original cross of white eyed male and a vestigial female are as 
follows (Class Results of 2011, 2012 and 2013 are attached in the Appendix):
