| Description: The rate of replacement of a recessive allele d by the dominant allele D by mutation alone. Even though the initial rate of replacement is high, it will take about 70,000 generations, or 1.4 million years, to drive the frequency of the allele d from 1.0 to 0.5. This curve is asymptotic, and will only reach zero at an infinite number of populations.
