Quizplus · Accepted Answer

In genetic equilibrium, the frequency of alleles remains constant from one generation to the next. Therefore, if the frequency of a recessive gene is 40 percent in the current generation, it will still be 40 percent in the next generation, assuming no outside forces (such as genetic drift or natural selection) are at work.
