  Genetic Structure of Guilan buffalo population, in the South and South western area of Caspian Sea in Iran, was characterized, using 14 microsatellite markers (CSSM019, CSSM029, CSSM033, CSSM038, CSSM041, CSSM043, CSSM047, CSRM060, CSSM061, CSSM062, CSSM070, BMC1013, BRN and ETH003). The average of observed and effective number of alleles across all loci was found to be 4.14 and 3.17, respectively. CSSM062 was the most polymorphic markers according to its effective number of alleles (4.69), expected heterozygosity (0.79) and Polymorphism information content (0.75). However, CSSM029 showed the lowest effective number of alleles (1.20), expected heterozygosity (0.50) and Polymorphism information content (0.37). Results showed that these markers were suitable in population genetics researches. The mean of observed and expected heterozygosity, Polymorphism information content and Shannon information index were equal to 0.90, 0.67, 0.61 and 1.22, respectively across all loci in the population. It was concluded that a high degree of genetic diversity exist in the Guilan buffalo populations.

  Polymorphic loci, genetic parameters (Polymorphic Information Content, heterozygosity, Shannon Index, the number of actual alleles, the number of effective alleles) and genetic variation within Balouchi sheep population located in Abbasabad station of Mashad, was assessed using 12 microsatellite markers. The Polymerase Chain Reaction (PCR) reactions were successfully done with all primers except for OarHH62 and OarAE64, one locus (CSSM059) was monomorph, whereas the other 9 loci containing CSSM018, CSSM006, BMS1004, BMS2361, BMS744, BMS799, BMS1316, BMS2213 and TGLA122 were polymorph with 6, 6, 4, 4, 5, 4, 2, 3 and 3 number of alleles, respectively. In this population, heterozygosity varied from 0.5 to 0.72; among 9 polymorphic loci, BMS1316 and BMS2361 had the most and the least diversity, respectively. The study of Shannon Index and Polymorphic Information Content (PIC) indicate the least and the most values for BMS1316 and BMS2213 loci, respectively. The most number of actual alleles were belong to CSSM018 and CSSM006 loci with 6 alleles and the least was belong to BMS1316 locus with 2 alleles. BMS2361 locus had the most and BMS1316 locus had the least number of effective alleles. All loci were at Hardy-Weinberg equilibrium (p< 0.005). In this population, average heterozygosity was estimated as 0.54. In general, it can be concluded that Balouchi sheep population of Abbasabad station in Mashad (in Iran) has approximately high genetic diversity with respect to the studied microsatellites and microsatellite markers have approximately high polymorphism and therefore can be used for genetic studies.
