Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu
als 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.
B, because species b has a higher percentage of survivors to old age than species C. Species a still has a higher rate than species C so the answer is b.
