The GH gene and BMP15 gene have been used as candidate genes for ­marker-assisted selection in different livestock species. Random blood samples were obtained from 180 Zel sheep breed to study genetic polymorphism of these genes. DNA was extracted from blood samples and a 365 bp fragment from the exon V of the ovine growth hormone gene and a 312 bp region from exon II of BMP15 gene were amplified by polymerase chain reaction. SSCP analysis showed three conformational patterns (A, B and C) for GH gene but for FecXL locus of BMP15 no banding patterns were observed in the animals tested. Results indicated that there were no significant associations (P>0.05) between polymorphism of the GH loci and lambing rate.
