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? 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 some mutation in the same wing-development gene. Each strain may have a different mutation, but the same gene is mutated in all trains in a complementation group.
c. They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.
