测定了猪Sus scrofa的线粒体基因组全序列。该序列的长度为16,679个核苷酸。然而，这个数字并不是绝对的，因为在不同分子的控制区中，GTACACGTGC基序的数量可变导致了明显的异质性。对线粒体基因组12个蛋白质编码基因的氨基酸和核苷酸序列进行了系统发育研究。分析表明，这种猪是母牛/鲸鱼分支的姊妹群，这使得偶蹄目恐龙变成了副甲虫。猪和牛/鲸之间的分裂是在6500万年前被分子测得的。
The complete mitochondrial genome sequence of the pig, Sus scrofa, was determined. The length of the sequence presented is 16,679 nucleotides. This figure is not absolute, however, due to pronounced heteroplasmy caused by variable numbers of the motif GTACACGTGC in the control region of different molecules. A phylogenetic study was performed on the concatenated amino acid and nucleotide sequences of 12 protein-coding genes of the mitochondrial genome. The analysis identified the pig (Suiformes) as a sister group of a cow/whale clade, making Artiodactyla paraphyletic. The split between pig and cow/whale was molecularly dated at 65 million years before present.
