According to the Hardy-Weinberg principle, the frequencies of alleles remain constant in a population, but only under certain conditions. Which of these events or conditions is most likely to maintain Hardy-Weinberg equilibrium? A. A natural disaster reduces the population to about 20 percent of its previous size.
B. Immigration from a neighboring ecosystem increases the population by 50 percent.
C. The alleles have no effect on which males and females mate and produce offspring.
D. The arrival of a new predator makes one of the alleles more advantageous than the other allele.
