As a volunteer in a genetics lab, Professor Uhura tasked you with testing the biparental mitochondria inheritance hypothesis in Drosophila for a metabolic phenotype that they are studying. Because you just got started in the lab, the professor tells you are not allowed to use any high-end high-tech resources to perform your experiments and to collect data. The only resources you have access to are the various stocks of Drosophila available in the incubators, the resources to feed the flies and to transfer the flies from vial to vial to perform crosses, and tools to measure the metabolic phenotype of interest.  Describe an experimental approach using crosses you could follow that could potentially provide you with data to support the biparental mtDNA inheritance hypothesis?
