Table 2. dN/dS ratios calculated for eight MHC class II genes in mammals (human, cattle, sheep, pig and seven cetacean species) and in cetaceans (seven cetacean species: the Yangtze finless porpoise, common bottlenose dolphin, Indo-Pacific bottlenose dolphin, killer whale, Yangtze River dolphin, sperm whale, and minke whale).
