Question

In a population of birds living on an island, the frequency of allele A1 is initially p = 0.4. In each generation, 10% of the individuals in that population are migrants from the nearby mainland, which has an allele frequency of pm = 0.6. a) Calculate the new frequency of A1 in each of the next two generations (generations 1 and 2) due to gene flow. Show your work. (2 points) Answer: b) Is the change in allele frequency in generation 2 greater than, less than, or equal to the change in generation 1? How can you explain that answer and what is predicted to happen to the allele frequency on the island after many generations? (2 points)
