Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant.
