  Allele frequencies of eight microsatellite loci as GUJ0001, GUJ0021, GUJ0034, GUJ0041, GUJ0049, GUJ0059, GUJ0070 and GUJ0097 was estimated for four strain of Japanese quail in Iran. Whole blood samples were collected from 200 individuals belonging to four strain (Pharach, Panda, Tuxedo and Golden).Total Genomic DNA was extracted by the GUSN-Silica Gel kit. The extracted DNA was amplified through Polymerase Chain Reaction (PCR). Of the eight microsatellite loci used in this study, two loci ( GUJ0001 and GUJ0041 ) were monomorphic in Panda and Texedo, respectively. The highest and the lowest PIC values belonged to GUJ0059 in Golden (0.815) and GUJ0041 in Panda strain (0.427), respectively. The expected heterozygosity varied between 0.708 and 0.849. All locus-strain combinations deviated from Hardy-Weinberg equilibrium except GUJ0041 in Pharach strain, GUJ0021, GUJ0034, GUJ0041 and GUJ0097 in Panda strain and GUJ0034, GUJ0049 and GUJ0070 in Golden strain (p<0.001). Results suggest the effectiveness of this set of loci for testing genetic relatedness.

  The aim of this study was to estimate the allele frequencies in polymorphic site of exon six of POU1F1 gene in three Iranian native and Holstein cattle. Genomic DNA was extracted from 3 Iranian native cattle breeds, including 97 Mazandarani, 87 Sarabi, 112 Golpaygani and also 110 Holstein cattle. A 451 bp fragment of intron 5 and exon 6 were amplified and digested with HinfI restriction enzyme. Frequencies of allele A were 0.37, 0.27, 0.34 and 0.21 for Mazandarani, Sarabi, Golpaygani and Holstein cattle, respectively. Significant differences in genotype frequencies were found between Mazandarani or Golpaygani and Holstein cattle. No significant differences in genotype frequencies were found between Sarabi and Holstein cattle. Transition A to G in nucleotide 1256 is responsible for HinfI(-) allele. No significant association was observed between POU1F1 polymorphism and milk production. Differences in allelic frequency between native Bos indicus breeds (Mazandarani, Golpaygani) and Holstein at the present study might be due to differences in origin breeds, low number of samples and/or as the effect of natural selection in native breeds.
