A newspaper story on AIDS reports that an allele (R) confers complete resistance to HIV when homozygous and that 1% of the human population is resistant (RR). The story also states that 20% of the population carries one copy of the resistance allele (i.e., is heterozygous). Is this a guess, an approximation, or an exact frequency, assuming that the population is at Hardy-Weinberg equilibrium?
