Evolutionary constraints and selection pressures on DEATH superfamily members. a The Ka and Ks values of DD, CARD, DED, and PYRIN gene pairs, and these gene pairs from sheep-goat, sheep-cattle, sheep-horse, goat-horse, goat-cattle, and hose-cattle are marked with different colours. The dashed line in squares indicates Ka/Ks = 1. b Comparisons of the Ka, Ks, and Ka/Ks values of different gene pairs. * P < 0.05, ** P < 0.01
