“…These obtained differentiation parameters are generally comparable with F st values of the fat-tailed Barbarine sheep breed (Sassi-Zaidy et al, 2014). The other investigated sheep population for pairwise genetic differentiation parameters showed values < 0.05, which, according to Hartl (1980), indicates a low differentiation among the population. Further, significant genetic differentiation observed ranged from 0.031 to 0.046.…”

A total of 75 individuals from five sheep populations in Kazakhstan were investigated based on 12 STR (short tandem repeat, also known as microsatellite) markers in order to study their genetic structure and phylogenetic relationship based on genetic distances. These sheep had a high level of genetic diversity. In total, 163 alleles were found in all the populations using 12 microsatellite loci. The mean number of alleles, effective number of alleles, and polymorphism information content (PIC) values per loci were 13.4, 5.9, and 0.78, respectively. Comparing the allelic diversity between the populations, the highest genetic diversity was observed in the Edilbay-1 sheep breed (8.333±0.644), and the lowest parameter was for Kazakh Arkhar-Merino (7.083±0.633). In all populations, there is a deficiency of heterozygosity. The largest genetic diversity was found in loci INRA023 and CSRD247 with 16 alleles, and the smallest polymorphism was noted for the locus D5S2 with 8 alleles. The level of observed heterozygosity was in the range 0.678±0.051 for Kazakh Arkhar-Merino and 0.767±0.047 for Kazakh fat-tailed coarse wool. The expected heterozygosity level range was from 0.702±0.033 for Kazakh Arkhar-Merino to 0.777±0.023 for Edilbay-1. When 12 microsatellite loci are compared, the OarFCB20 locus showed the highest level of genetic variability. Excess of heterozygosity was observed at three loci; MAF065, McM042, and OarFCB20. The highest genetic distance was observed between Kazakh Arkhar-Merino and Edilbay-1, whereas the genetic distance between Edilbay-1 and Edilbay-2 is the smallest using Nei's standard genetic distance. The Edilbay-1 sheep breed possesses the largest genetic diversity among these five populations.

“…Mean number of alleles and polymorphic information content values observed in the present study were higher than values obtained from the other sheep breeds (Yilmaz et al, 2015;Guang-Xin et al, 2016;Kırıkçı et al, 2018). This situation can be regarded as an important indicator of high genetic diversity in sheep populations studied.…”

Assessment of genetic diversity of Turkish and Algerian native sheep breedsAbstract: In Algeria and Turkey, the sheep production systems are based on the under extensive rural conditions and their genetic management has led to increased homozygosity and hence productivity loss. The identification of inter-breed and intra-breed genetic diversity plays a key role in the shaping of conservation and breeding programs. The present study was conducted to investigate the genetic diversity of native sheep breeds reared in Turkey and Algeria. A total of 240 animals from four Algerian (Hamra, Ouled Djellal, Sidaou, and Tazegzawt) and four Turkish (White Karaman, South Karaman, Karacabey Merino, and Kıvırcık) native sheep breeds were genotyped with fourteen microsatellite markers recommended by FAO. A total of 340 alleles were detected from fourteen markers studied. All the eight breeds exhibited moderate to high levels of genetic diversity, with a slight superiority of the Algerian sheep breeds. Overall FIS value was low, but highly significant (p < 0.001). It may have been due to the high inbreeding within the population. The mean global coefficient of gene differentiation (GST) showed that approximately 94.0 % of the genetic variation was within-population. The highest number of private alleles with a frequency above 5 % was observed in Ouled Djellal sheep. Structure analysis of populations studied revealed the most appropriate K with four genetic clusters. As the result, the dendrogram showed that the Algerian sheep breeds were completely separated from the Turkish sheep breeds furthermore the Bayesian clustering revealed a high level of admixture, especially in Algerian sheep populations. Pregled genetske pestrosti turških in alžirskih avtohotnih populacij ovacIzvleček: Sistemi reje ovac v Alžiriji in Turčiji temeljijo na ekstenzivni kmečki reji, upravljanje s temi populacijami pa je privedlo do povečanja homozigotnosti in s tem do poslabšanja proizvodnih lastnosti. Ocena medpasemske in znotrajpasemske genske pestrosti igra ključno vlogo pri oblikovanju programov za ohranjanje teh pasem. Pričujoča študija je bila izvedena z namenom raziskovanja genske pestrosti avtohtonih pasem ovac v Turčiji in v Alžiriji. Skupno 240 živali štirih alžirskih (hamra, ouled djellal, sidaou in tazegzawt) in štirih turških (white karaman, south karaman, karacabey merino in kıvırcık) pasem je bilo genotipiziranih s štirinajstimi mikrosatelitnimi markerji, ki jih priporoča FAO. Na štirinajstih analiziranih markerskih lokusih je bilo zabeleženih 340 alelov. Vseh osem pasem je imelo zmerno do visoko stopnjo genske pestrosti z rahlo prevlado alžirskih pasem ovac. Skupna vrednost FIS je bila nizka, vendar statistično značilna (p < 0,001). To je verjetno posledica visokega inbridinga v populaciji. Povprečni globalni koeficient diferenciacije genov (GST) je pokazal, da je približno 94,0 % genske pestrosti znotraj populacije. Največ privatnih alelov s pogostostjo nad 5 % je bilo ugotovljenih pri ovcah pasme ouled djellal. Analiza strukture populaci...

The objective of this study was to assess the genetic diversity and population structure of goats in the Yangtze River region using microsatellite and mtDNA to better understand the current status of those goat genetic diversity and the effects of natural landscape in fashion of domestic animal genetic diversity. The genetic variability of 16 goat populations in the littoral zone of the Yangtze River was estimated using 21 autosomal microsatellites, which revealed high diversity and genetic population clustering with a dispersed geographical distribution. A phylogenetic analysis of the mitochondrial D‐loop region (482 bp) was conducted in 494 goats from the Yangtze River region. In total, 117 SNPs were reconstructed, and 173 haplotypes were identified, 94.5% of which belonged to lineages A and B. Lineages C, D, and G had lower frequencies (5.2%), and lineage F haplotypes were undetected. Several high‐frequency haplotypes were shared by different ecogeographically distributed populations, and the close phylogenetic relationships among certain low‐frequency haplotypes indicated the historical exchange of genetic material among these populations. In particular, the lineage G haplotype suggests that some west Asian goat genetic material may have been transferred to China via Muslim migration.
