Sequence alignments showing base substitutions and indels in the mtDNA D-loop region (582 bp) of 143 Portuguese dogs. Sequence codes and numbers are given in the first column, with asterisks for previously published sequences. Only variable sites are shown, with sequence positions given above. Nucleotide positions are numbered according to Pereira et al (2004). Identity with the reference sequence (A19) is denoted by a stop, substitution by a different base letter, and deletions by a dash. Last four columns indicate the number of individuals in each breed (CL-Castro Laboreiro Dog; SE-Serra da Estrela Mountain Dog; PS-Portuguese Sheepdog; AC-Azores Cattle Dog).
