Complex tests of DNA sequences, genetic research, and the use of specific DNA polymorphisms as genetic markers have all advanced rapidly in recent years. It is widely used in DNA-based parental testing. Therefore, it has replaced the blood types routinely used in pedigree tests. The study aimed to evaluate the 14 microsatellite loci in the study in terms of paternity test parameters and to investigate the usability of the relevant loci in determining the parentage of the Karacabey Merino breed. In this study, paternity testing was performed on 5 rams of the Karacabey Merino breed and their probable 98 offspring using 14 microsatellite loci. A total of 290 alleles were observed in the study. The observed heterozygosity ratio (Ho) based on loci was between 0.82 and 0.98, and the expected heterozygosity ratio (He) was between 0.87 and 0.93. Individual exclusion probability (PE) values for the loci were calculated to be between 0.596 and 0.761, with combined exclusion probability (CPE) values of 0.99999995. According to the results of the study, paternity tests using 14 microsatellite markers in Karacabey Merino sheep can be used with high accuracy. © 2023.
