The original mainland population of a bird species has an allele frequency of 0.5 for a particular beak size allele, L. A small flock of birds, containing only 10 individuals, is blown off course and establishes a new population on a remote island. By chance, the frequency of the L allele in this founding flock is 0.8.
Describe how the founder effect has influenced the allele frequency in the island population, and how this differs from the effect of natural selection on allele frequency.
