Which practice is most likely to result in a change in the Hardy-Weinberg equilibrium of a population or geographic area?
A)Random mating from within the established population
B)Geographic isolation of the established population
C)Assimilation of immigrants into the existing population
D)Preponderance of autosomal-dominant traits in the existing population

The first criterion for Hardy-Weinberg equilibrium is no migration (out from or into the existing population. Thus, the arrival of a group of immigrants who are assimilated into the established population represents a loss of the first criterion. As assimilation occurs, even with random mating, the new population adds to the existing gene pool. Geographic isolation of the established population contributes to Hardy-Weinberg equilibrium by reducing the chances for migration. A preponderance of autosomal-dominant traits neither contributes to nor takes away from equilibrium.
