Percent identities between each intron and exon in the herring (H), rainbow smelt (S) and sea raven (SR) AFP gene sequences.

The columns labeled with % are the identities. The first (no gaps) is calculated by pair wise exclusion of gaps and the second (gaps) is calculated over the length of the alignment, gaps included. The column labeled with bp shows the total length of each alignment (first no gaps/second with gaps). The second intron is not included as large portions of the sequence are probably not homologous.
