atrogularis.
Of the 77 sequences, 30 were non-translatable due to indels or the presence of stop codons resulted changes in the reading frame. Sequences were thus presumed to be pseudogenes. The number of identified pseudogenes within the four species ranged between three to five in most individuals of study population and six of the thirteen pseudogene sequences were found to be identical in three individuals from the population of sampled species. We cannot ignore the likelihood that some of the identified pseudogene sequences may be due to PCR or sequencing artifacts, as such events would more often result in nonfunctional sequences. The nucleotide deletion result in loss of 3 amino acids was obvious in Tuna-MHCI*PS 07-9 and Tueu-MHCI*PS 01-04 andTueu-MHCI*PS 08. Both nucleotide deletion, frame shift mutation and premature stop codons were detected in Turu-MHCI*PS 01,03 andMHCI*PS 09 at amino acid 33 encoding Exon 3. Loss of 3 amino acids was at position 78 was detected in Tuat-MHCI*PS 05 andTuat- MHCI*PS06.
