2- It is VERY VERY important to read the uploaded files.

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..
