AI Article Synopsis
- * Researchers used PCR amplification and detected the amplified products, finding extremely high values for genetic diversity in the loci examined.
- * The findings indicate that these STR loci are highly polymorphic, making them ideal for identifying individuals and establishing paternity in Tibetan Mastiffs. The results will aid in developing a DNA polymorphism database for these dogs.
Article Abstract
Objective: To explore the genetic polymorphisms of 16 STR loci from 449 Tibetan Mastiffs in order to set up gene polymorphism database of Tibetan Mastiff.
Methods: The PCR amplification was performed using the 16 STR loci fluorescent multiple amplification kit for dog. The amplified products were detected and statistically analyzed.
Results: In the 16 STR loci from 449 Tibetan Mastiffs, CDP was 0.999 999 999 999 999 and CEP was 0.999 997 795. Except FH2010 (10 alleles), PEZ21 (12 alleles), and PEZ05 (13 alleles), the other STR loci had more than 15 alleles. In the 16 STR loci, H was > 0.5 and PIC was > 0.7.
Conclusion: The 16 STR loci have high polymorphism to be suitable for individual identification and paternity testing of Tibetan Mastiff. The data obtained through this study can be used to establish DNA polymorphism database of Tibetan Mastiff.
