Here is one question with two sub-questions. Thank you for your time. 

Suppose researchers identified two Drosophila melanogaster mutant phenotypes. One phenotype is called maniac and the other
is called shiny. In order to determine the mode of inheritance of the mutant allele responsible for each phenotype, males that
have both mutant phenotypes are mated with wild-type (wt) females to produce F, progeny. Then, the F, progeny are mated
together and the F2 progeny are scored.
