While working in a genetics lab over the summer, you isolated a true-breeding strain of wingless drosophila. after sharing your
results with your mentor, you learn that six other true-breeding strains of drosophila with the same mutant phenotype have been isolated independently in your lab. your mentor asks you to determine if the mutants belong to the same complementation group. what is true about flies that belong to the same complementation group? what would be the outcome of crossing two strains of wingless flies that belong to the same complementation group? select all answers that apply to the two questions?
If the two mutations are on different genes, mating together, the progeny will have the function restored.else if the mutation is the same, the function shall remain and wingless progeny will be visible.
Explanation:Just to explain shall use an example.Suppose there are two different mutations . The genes be called as 1 and 2.Also assume that they make proteins 1 and 2.Now the two proteins shall perform two different functions but the end wingless character is maintained.Now suppose fly 1 has mutation 1 and protein 1 is not being synthesized .But yet it is being synthesized in fly 2, that has a mutation in protein 2.when the two are mated protein 1 comes from fly 2 and protein 2 comes from Fly 1, as a result the two proteins and their functional copies are available and hence all functions completed and the fly develops a wing.The essential thing to understand is that if two flies have two different mutations both will have the two proteins from the other fly and the function of the protein will be completed.
As you know (if you do), when two animals mate, they combine their genes to make a baby. So of their skin colors are different like one is brown and one is white, then you get a baby that would look brownish white or have spots that are brown or white.
