Treatment of a human with an antiviral drug (A or B) reduces by 50% the survival of any genotype not carrying the matching resistance allele. In the absence of antiviral drug treatment, the fitness of the least fit genotype is: 50 100 200 400 800 In the presence of antiviral drug (anti-V[B]), the relative fitness of the least fit genotype is: 0.1 0.33 0.50 0.67 0.9 In the presence of antiviral drug (anti-V[A]), the relative fitness of the least fit genotype is: 0.1 0.25 0.5 0.75 0.9
