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?

In this scenario, there is no natural selection or new mutations, so the only factor influencing changes in allele frequency is genetic drift. Because the population is large and random mating is occurring, genetic drift is less likely to cause significant changes in allele frequency. Therefore, p will remain more or less constant over time.
