Patterns of genome evolution. a Magnitude of W → S bias within faster evolving regions (FRs) identified in pairwise comparisons between cat and the lynx ancestor and between Iberian and Eurasian lynx. b Heterozygosity in regions defined as FRs in Eurasian or Iberian lynx. Iberian lynx values are reported for the whole species and for the reference individual. Whereas FRs in cat and the lynx ancestor are associated with higher W → S biases, FRs in both lynx species are associated with reduced heterozygosity and fixation of ancestral polymorphisms. c dN/dS ratios estimated for different mammalian lineages. Increased ratios in lynx indicate the relaxation of purifying selection following the divergence of Iberian and Eurasian lynx
