Figure 4From: Differentiated evolutionary rates in alternative exons and the implications for splicing regulationAverage (a) non-synonymous (dN) and (b) synonymous (dS) substitution rates (y-axis) for different minimum percentage identity conservation values (x-axis). For each percentage identity value, we calculate the average dN, dS and corresponding standard error bars, for all the exons of each subgroup having greater or equal identity conservation.Back to article page
