Correlation between SNP A/S ratios and expression parameters. Genes were grouped into bins of roughly nine equal intervals according to several expression measurements from a microarray experiment, and the SNP A/S ratio was obtained for each bin. Error bars represent 95th percentile confidence intervals from bootstrap resampling. (a) Negative correlation between SNP A/S ratios and mean mRNA expression levels. (b) Negative correlation between SNP A/S ratios and peak mRNA expression levels. (c) Negative correlation between SNP A/S ratios and expression breadth. (d) No correlation between SNP A/S ratios and expression tissue specificity.
