The Table Lists the Frequencies of an Allele (A) at a Locus

Multiple Choice

The table lists the frequencies of an allele (A) at a locus and the average fitness of carriers of that allele at each frequency in four haploid populations. The fitness of the other allele (a) is always 0.9, regardless of the frequency of the alleles.In which population can both alleles be maintained?

A) Population 1
B) Population 2
C) Population 3
D) Population 4
E) None of the above; selection will be unable to maintain genetic variation in any of these populations.
