Question

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?

Answer 1

Answer:

=> There will be mutation of gene in each strain.

=> The offsprings are wild type.

Explanation:

So, we are given the following main or Important information or data which I going to assist us in solving this particular Question or problem:

=> There is an isolated a true-breeding strain of wingless Drosophila.

=> " six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in the lab."

Therefore, the flies that belong to different complementation groups will cause MUTATION TO OCCUR ON THE SAME GENE.

Mutation will occur because here we have dual but different genomes and when you take a look at these genomes they both have a trait of recessiveness and this combination of the genomes will cause the mutation.

Quick note: on the strain, occurence if different mutation might or might not occur.
