Genetic Effect of IGF1, PIT1 and Leptin Genes on Wool Weights in Makooei Sheep

The study of candidate genes, based on physiological results, is a critical tool to detect genes to be applied in marker-assisted choice processes. On the topic of sheep gene polymorphism knowledge the ovine IGF1, PIT-1, Leptin genes was analyzed as a probable genetic marker for growth characteristics in sheep. In the checked Makui sheep population, definitive calculational results demonstrated that the IGF1, PIT-1, Leptin genes great position in wool1 weight. Measurement of associations between genotypes as well as wool weights was performed with 100 tests. The measurement of a relation between these SSCP models with wool1 (A Fleece mass at lifetime), wool2 (Wool mass dual years of lifetime), wool3 (Fleece mass at three years of lifetime), wool4 (Fleece mass at four years of lifetime) showed a certain aftereffect of the entire models with wool1 mass in one year (A fleece mass at lifetime). Individuals with the L4, P4 additionally I2 of Leptin, PIT1 also IGF1, genes had a dominance wool1 mass (A fleece mass at lifetime) when contrasted to those of individuals with extraneousness genotypes. In addition the affects showed L3, P2 and I3 had mark down wool1(A fleece mass at lifetime) mass specialization when contrasted to those of individuals with difference genotypes. In the end, these events demonstrate that wool weights later one year of lifetime may be mainly influenced surrounding agents like Nutrition.
