Genetic polymorphism study of growth hormone gene (GH1) from exons 2 and 3 in autochthonous Carpatina goat breed.

The goats have specific characteristics, as a result of their great adaptability to the environment and food. Considering the association between GH gene polymorphism and the growth traits, the present study aimed to highlight the presence of polymorphisms on exons 2 and 3 of the GH1 gene in Crapatina breed and also the genotype and allele frequencies. Using PCR-RFLP technique were found 3 genotypes in this population: AA (uncut 422 bp fragment), BB (366 bp and 56 bp fragments) and AB (422, 366, and 56 bp fragments). The AA genotype frequency was 7%, 48% for the genotype AB and 45% for genotype BB. Also, in this population gene A appeared with a frequency of 31% and gene B with a frequency of 69%.
