Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individuals that have two copies of the recessive allele have the condition. If the p allele is found in 11 percent of the population, what percentage of the population is carrying the P allele?

A. 89 percentB. 94 percentC. 67 percentD. 11 percent

Considering the question is asking only for the percentage of the P allele, then the correct answer is A - 89 percent.

This is correct because we always have a combination of 2 alleles, either PP, Pp or pp. If from all these the p allele is found only in 11% then the remaining 89% are from the P allele.
