[i] Insertions and deletions in intron 2 of the PrPgenes. For each species the total number of bases in intron 2 occupied by species-specific interspersed repeats was calculated. The size of the deletions was calculated from the size of the orthologous regions in the other species, disregarding species-specific repeats in those regions. In all three species one comes to an estimate for the length of this intron before the mammalian radiation of 9.1 kb.
