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 different complementation groups? What would be the outcome of crossing two strains of wingless flies that belong to different complementation groups? Select all answers that apply to the two questions. a.They all have the same mutation in the same wing- development gene. All flies in a complementation group have identical DNA sequences for this gene. b.They all have a mutation in one of the wing-development genes. Each strain may have a different mutation within the gene, but the same gene is mutated in all strains in a specific complementation group. c.They all have a mutation in one of the wing-development genes. Each strain will have a mutation in a different gene, but all strains within a complementation group have the same phenotype. Strains in different complementation groups will have mutations in different genes. d.Some offspring will be wild-type, and some will be wingless. e.All offspring resulting from strains crossed from different complementation groups will be wild-type. f.All offspring will be wingless because complementation did not occur. g.All offspring resulting from strains crossed from different complementation groups will be wingless.
