Apopulation carries two alleles at a locus. one allele has a miniscule fitness advantage. what is the long-term fate of the locus if natural selection is the only important evolutionary force? group of answer choices the population size will decrease. the population size will increase. eventually the beneficial allele will be fixed by natural selection. both alleles will remain in the population at a ratio proportional to the fitness difference. the allele at a disadvantage will mutate to improve to the fitness level of the other allele.
