The objective of the present work was to identify and validate single nucleotide variations located in candidate genes to growth traits in tilapia (Oreochromis niloticus). Two transitions were identified in the promoter region of the growth hormone gene (GH); eight nucleotide changes were identified in introns and promoter region of the IGF-I gene; and a transition (T/C) was identified in the Myogenin gene (MyoG). The highest genotypic frequency (0.8) for GHpA1 and MyoG was found in the GG and TT […]

The polymorphism of the growth hormone gene (bGH) was studied in 211 Nellore pure breed bovine males to estimate the genotype and allelic frequencies and possible associations of the gene with weight traits. For this study, body weight data were collected at birth, weaning and monthly from 10 to 16 months of age. Additionally, weight gains from birth to weaning and weaning to 16 months of age were calculated. DNA was extracted from blood samples and the animals genotyped for […]
