Normalized time (generations) to first appearance (vTf) versus number of loci λ required to be changed to yield the multiresidue (MR) feature. In all cases, the curves are determined from equation 3. v =0.01. Reproduction was deterministic. Filled circles, N =1; open circles, N =10; filled inverted triangles, N =100; open inverted triangles circles, N =1000; filled squares, N =10,000; open squares, N =100,000. (Upper left) ρ=1; (upper right) ρ =2; (lower left) ρ =4; (lower right) ρ =10. Each point is the average of 100 repetitions.
