Conservation of upstream regulatory regions as measured by dSM. (a) Distribution of dSM scores between all paralogous pairs, according to H3K27me3. The dashed vertical line shows the dSM value at the fifth percentile of the random pairs (0.94). (b) Frequency of paralogous pairs with dSM lower than the fifth percentile cutoff.
