The data used in Fig. 3 for the standard gene model and standard rates of mutation and crossing over were applied to estimates of the parameters of positive selection and synonymous site diversity from models with (+) or without (−) selective effects on UTRs, BGS, and GC. When GC was present, the low rate of Fig. 3 was assumed. πr max is the maximum value of the mean synonymous site diversity of a gene, relative to its value in the absence of selection; πr mean is the corresponding mean value over bins. Other variables are defined in the text.
