Table 2.

Linear regression model with the response variable as the deviation from nucleotide composition equilibrium (GC*-GC) and explanatory variables as the per site and year divergence rate, the transition to transversion ratio and chromosome length (GC*-GC ~ div. rate + ts:tv + length). For each telomere, we consider four values corresponding to the four external branches of the great ape phylogeny. In total, we consider N = 100 estimates for autosomes (across 25 alignable telomeres) and N = 4 estimates for PAR1
