Figure 7.—
The effect of neighboring genes on background selection without crossing over. Both plots show the mean B for a focal gene, with the same features of neighboring genes as in Figure 5. However, crossing over is assumed to be absent and curve thickness denotes the rate of gene conversion rg (thick, 5 × 10−6; medium, 2.5 × 10−6; thin, 0.5 × 10−6). Line type represents the mutation rate (dotted, 2 × 10−9; dashed, 4 × 10−9; solid, 8 × 10−9) and the highlighted line indicates a typical gene (dashed line with medium thickness). (A) Fixed selection coefficient. (B) Average of 100 samples from the DDME.
