Question
A very large population of rats exists in a South American port city. We know from sampling the population that the glicidolukage locus (GDL) has four enzymatic variants (alleles A-D) occurring at the following frequencies:
_
f(A)=0.20
f(B)=0.55
f(C)=0.05
f(D)=0.40
_
Now imagine that a ship sets off from the South American port city carrying four rats from the city. The ship calls at a Pacific island that did not have a rat population. All four rats disembark on the Pacific island and start a new rat population on the island. Which of the GDL alleles do you expect to be represented in the new rat population that establishes on the island (from most to least likely)?
