You are studying a particular mutant fly which has misshapen wings. You believe you know which gene has been mutated to cause the misshapen wing phenotype but you do not know exactly what the mutation is (i.e. point mutation? Deletion? Insertion?) What is the best experimental protocol to determine the sequence of the mutated gene?
