P, Position within the site. Boldface denotes cases where the nc → c change has the lowest value of all the possible changes involving that nucleotide and the value is statistically significant (P ≤ 0.01). The P-value was computed by simulating changes at alternative splice sites using the rate of change estimated from constitutive sites.
