Significant associations of polymorphisms in the growth hormone gene with growth traits in common carp (Cyprinus carpio)

The growth hormone (GH) gene is considered to play an important role in the growth of fish. In this study, the common carp GH gene was characterized to detect gene variation at these loci in relation to economic traits in common carp. Six single nucleotide polymorphisms (SNPs) were detected in GH gene, while they were all missense mutations. Statistical analysis indicated that the GH polymorphism was significantly associated with the body length, body weight, AGR and SGR in common carp.
