Fragmented mitochondrial genomes of the rat lice, Polyplax asiatica and Polyplax spinulosa: intra-genus variation in fragmentation pattern and a possible link between the extent of fragmentation and the length of life cycle

Table 2 The longest stretches of identical sequence shared by mitochondrial genes in two rat lice, three human lice, two pig lice, which have fragmented mitochondrial genomes, and six other species of bilateral animals that have the typical mitochondrial genomes
