Fig. 2From: Evolutionary dynamics of pseudoautosomal region 1 in humans and great apesA Distribution of per site and year (PY) divergence rates for autosomal (A; N = 25) telomeres and PAR1 in the four external branches of the great ape phylogeny; human (H), chimpanzee (C), gorilla (G), and orangutan (O). Telomere 8L in both the human and gorilla lineage exceeds the PAR1 rate. B Distribution of AT→GC/GC→AT substitution count ratios across telomeres. C Distribution of the difference between the equilibrium GC proportion (GC*), expected given the inferred AT→GC and GC→AT substitution rates, and current telomeric GC proportion. The red dashed lines indicate the expectation under nucleotide composition equilibriumBack to article page
