We know that frequency of recombination is proportional with the distance between the genes on the chromosome. Therefore when the recombination rate is higher that means the distance between the genes on the chromosome is bigger. If the recombination rate is lower that means the genes are closer to each other on the chromosome. In this case the cross over rate is half the normal rate in the wild-type. That means that on the genetic map the distance between the two genes on the wild type will be twice bigger than the genes of the mutated Drosophila.
The answer is B. Paleozoic
This era was the first era where insects, amphibians, and reptiles roamed the Earth.
Hope this helps!
Idk but you can ask google and I'm sure they will tell you
