Problem
Practice with the gene flow (migration) model: Totally simplified, hypothetical scenario here: You know that frequency of the 5 allele in the sickle cell system in Indianapolis has been 15% for many generations lie, in the long-term). However, when Indy was first settled, the frequency was 5%. Assuming that the 5 allele has increased due to migration from another source population, what was the initial frequency of this allele in the other population?
