So what do you conclude about the evolutionary power of mutation (all by itself) to change allele frequencies?
This one is quick and easy. Click reset. Then make the mutation rate of A1 to A2 something that is high but biologically plausible, e.g. 0.0001, and the reverse mutation rate A2 to A1 just leave at zero. This simulates mutation as strongly as is biologically realistic, so we are giving mutation the best chance to show us what it can do. Click run, what happens?
So what do you conclude about the evolutionary power of mutation (all by itself) to change allele frequencies? Is mutation an important evolutionary force (obviously it is incredibly important in providing genetic variation for selection to act upon, but is mutation itself a significant force causing microevolutionary change)?
