Abstract: To investigate and assess the aggressive behavior phenotypic spectrum of Turpan gamecock and SNP of their behavior related genes, this study adopted the methods including mirror fighting and pair fighting to observe aggressive behavior phenotypes of 12 adult Turpan gamecock, and PCR-SSCP analysis about monoamine oxidase A (MAOA) gene in exons 1 and 2 of 103 Turpan gamecock and 71 New Romain chicken. The results showed that both methods of fighting strength of aggressive behavior phenotype sort basically the same, indicating that the behavior of aggressive behavior spectrum could be used for the preparation of aggressive behavior in Turpan gamecock fighting strength of phenotypic assessment. MAOA1 polymorphism in Turpan gamecock and New Romain was no difference after detection, but on the MAOA2, the polymorphism was not entirely consistent, suggesting MAOA2 might be had a certain correlation with Turpan gamecock aggressive behavior.
