Imagine that you are studying a very large population of moths that is isolated from gene flow. A single gene controls wing color. Half of the moths have white-spotted wings (genotype WW or Ww), and half of the moths have plain brown wings (ww). There are no new mutations. Individuals mate randomly, and there is no natural selection on wing color. How will p, the frequency of the dominant allele, change over time?
