Fig. 3. Nucleotide alignment of the 5' end of the first intron of Tmyostatin 1 and Tmyostatin 2 showing an additional insertion (in brackets) of a 509-nucleotide (nt) fragment within the first intron of the Tmyostatin 1 gene. Identity is indicated by a vertical line. The arrow indicates the exon/intron boundary. Accession numbers are AF278606 for intron 1 of Tmyostatin 1 and AF278607 for intron 1 of Tmyostatin 2.
