ABSTRACT
The association of growth hormone (GH) gene polymorphisms with growth traits such as body weight (BW), chest girth (CG), body length (BL), and body height (BH) in TC (TC) sheep has an important role in the genetic marker-based selection program (MAS). The study aimed to examine the association of GH genes with the growth traits of TC sheep. The material used is 42 ewes. The research method is a survey. The length GH gene is 661 bp. DNA fragments were amplified, and the genotype was identified using the PCR-RFLP. The results showed that SNP was found at position c.573 G>A. The Hardy–Weinberg equilibrium shows that the population is in balance. The genotype frequencies of AA, AG, and GG were 0.24; 0.55; and 0.21. The frequencies of the A and G alleles were 0.51 and 0.49. There was an association between the genetic diversity of the GH gene and growth traits (p<0.01).
