Awassi Breed

Genotypes and allele frequency values ​​were studied to determine the genetic diversity of three microsatellite markers (BM1329, BM134 and CSSM66) in two local Iraqi sheep breeds (50 Awasi ewes (AW) and 50 Naimi ewes (NA)) and breed in one Agricultural Stations in middle of Al-Furut Iraq (Karbala Governorate). The Genetic analyses for the study were carried out at the Biotechnology Research Center /  Al-Nahrain University using PCR technology to obtain alleles for the studied microsatellites. The results of this study indicate that there is a multiplicity of genotypes and alleles resulting from these markers among the members of the single breed and between the studied breeds. It was revealed that the allele frequency values showed the presence of alleles dominant on the rest of alleles produce in this sample studied, the BM1329 microsatellite of the Awassi breed produced the dominant allele frequency in 195(0.25) and 320 (0.25), While in the Naimi breed were the values ​​of the dominant allele frequency of the195(0.22), 220(0.21) and 230(0.24), and the dominant allelic frequency of (BM134) marker in the Awassi breed was 118 and 135 and repeated (0.21 and 0.26, respectively). For CSSM66 microsatellite, the dominant allelic results and their allelic frequency values ​​were (195 (0.20), 205 (0.23) and 220 (0.25)) for Awasi breed, whereas it was 180 (0.24), 195 (0.28) and 220 (0.22) for Nuaimi breed. These results enable us to use these markers as a means of determining the diversity and genetic relationships between individuals of a single breed as well as between breeds.

Abstract. The state of the local breeds of farm animals is increasingly precarious worldwide because of the aggressive introduction of breeds with improved economical traits. The preference of the breeders for local breeds is due to their higher adaptability to the particular climate and relief conditions of the mountain areas, to the high rate of assimilation of the feeds from these regions and to their increased resistance to diseases. This study analyzes the genetic variation of the main four local Romanian sheep breeds (Tsurcana, Tsigai, Ratska and Teleorman Blackhead) in terms of stock and economic importance, using 18 microsatellite markers. The mean number of alleles per locus was of 9.764. The values of genetic diversity parameters exhibited a high degree of polymorphism for the analyzed breeds, although inbreeding was highlighted particularly in Tsurcana and Tsigai. These breeds also showed an intense gene flow among them and were less differentiated in comparison with Ratska and Teleorman Blackhead. The results of this study may be useful for breeding programs and conservation plans since the genetic resources of the local breeds must be preserved so as to maintain an adequate level of biodiversity in animal husbandry.

Hardy Weinberg Equilibrium

In this study, six microsatellite markers were adopted to detect the genetic diversity and analyze the genetic distance of three Chinese indigenous sheep breeds. The results showed that 161 alleles were detected in the three breeds of sheep populations, and the average effective number of alleles, the average polymorphism information content (PIC) of six microsatellite markers in fat-tailed sheep, small tailed han-sheep, Yuxi fat-tailed sheep were 5.8844, 6.3103, 4.8017 and 0.7463, 0.7790, 0.7140 respectively. Five markers were highly polymorphic except marker ILSTS011 which gave moderate polymorphic. Except markers OarFCB48, OarFCB304 and BL1038, the other three microsatellite markers deviated significantly from the Hardy-Weinberg Equilibrium (P
