“…It can be said that there is loss of heterozygosity in four microsatellite loci studied considering F IS value is also known as the inbreeding coefficient. It is noteworthy that obtained general mean of F ST value is higher than earlier studies (Cemal et al 2013;Ben Sassi-Zaidy et al 2014;Ocampo et al 2016) and lower than others (Sodhi et al 2006;Yilmaz et al 2014). The differences between the previous literature and the present study were mainly due to non-comparative aspects such as studied microsatellite and breed differences.…”

“…It was an important parameter in the study that the F IS and F IT values were considerably lower than the numerous sheep breeds such as Colombian sheep breeds (Ocampo et al 2016), Tunisian native sheep breeds (Ben Sassi-Zaidy et al 2014) and Turkish native sheep breeds (Yilmaz et al 2014), and higher than the values reported by Cemal et al (2013). It can be said that there is loss of heterozygosity in four microsatellite loci studied considering F IS value is also known as the inbreeding coefficient.…”

Exposition of variations between breeds is very important for genetic diversity. Determination of this variation is needed to reveal population structure and relationship between populations and planning national breeding and conservation programmes. This study was carried out in 296 animals from 12 different local sheep breeds (Barbarine, Ouled Djellal, Ifilene, Srandi, Darâa, Rembi, Berbere, Taâdmit, Hamra, Sidaou, Tazegzawt and D'men) reared in different regions of Algeria. Fifteen microsatellite markers were used to determine between breed genetic diversity. The population of 12 sheep breeds studied from Algeria exhibited a high number of alleles (24.67) and polymorphic information content (0.90). Observed heterozygosity values were lower than expected for all molecular markers except INRA0123 locus. Obtained G ST value from the present study indicated that 1.9% of total genetic variation resulted from the differences between the breeds. The present study supplied important information to understand between breed genetic differences. Moreover, it has provided the opportunity to discuss with previously reported results. In light of these findings, it can be said that studied microsatellite markers can be successfully used to determine genetic diversity and population structure in Algerian sheep breeds.

“…Comparable genetic variability has been reported by E. Guang-Xin et al (2016) and R. Ocampoet al (2015) in 14 native Chinese sheep and Colombian sheep breeds [29][30]. Among the populations, Fixation index (F) varied from 0.035 for Kazakh Arkhar Merinos to 0.058 for Edilbai (0 < F < 1) [31]. As a result, Fixation index revealed the random-mating events in all populations.…”

The genetic structure of three Kazakh sheep breeds was examined by using 12 microsatellite loci. A total of 144 alleles were detected from the 12 STR loci, with a mean value of 12.0. The highest allele diversity was found at the locus CSRD247 (16 alleles). PIC value showed that all studied STR markers are more informative and appropriate for genetic analysis of three Kazakh sheep populations. Beside of INRA006, all markers had high level of genetic variability. As Fixation index shows, the excess of the heterozygosity was observed only in loci MAF065. Obtained number of private alleles in Edilbai, Kazakh Arkhar Merino and Kazakh Fine-wool sheep were 25, 17 and 15 respectively. Genetic diversity was higher in Edilbai population than in other two populations. The genetic variability was lower in Kazakh Arkhar Merino sheep than in the Edilbai and Kazakh Fine-wool sheep breeds. The genetic distance was the largest between Edilbai and Kazakh Arkhar Merinos. Also, the moderate differentiation was observed between Edilbai and Kazakh Arkhar Merinos.

“…Estimates of diversity in populations of sheep from Colombia presented mostly low heterozygosity, with values of Ho below the values of He, with means of 0.68 and 0.77 respectively [ 26 ]. In that study, the authors used 513 animals from 13 breeds from 56 farms, and values indicative of diversity were lower than those found in our study.…”

BackgroundBecause of the influence of genetics on animal production and the risk of losing genetic diversity of naturally adapted breeds, this study evaluated the genetic diversity of sheep of the Morada Nova breed belonging to an animal science institute in Brazil. The herd in question is one of the country’s most representative of the breed. Samples of DNA extracted from the plasma of 61 animals were used for later analysis of the genotypes using microsatellite molecular markers.ResultsThe polymorphic information content was 0.66, the observed heterozygosity was 0.65 and the fixation index was 0.048. According to the results, there is moderate genetic diversity in the studied population, suggesting the implantation of breeding programs aimed at conservation of the observed genetic diversity.ConclusionThe results obtained in this study will be of great importance to decisions on herd structure, besides contributing to other work to be carried out at the research center.
