“…Microsatellite markers belong to a class of neutral markers, which have rich polymorphism in population and are widely distributed in the genome; therefore they are suitable for genetic diversity analysis. Previous studies indicated that microsatellite markers had been well used to assess genetic diversity and population structure of sheep breeds (Di et al, 2012;Dotsev et al, 2018;Madilindi et al, 2019;Vargas et al, 2018;Laoun et al, 2020;Ullah et al, 2020) and goat breeds (Carvalho et al, 2015;Câmara et al, 2017;E et al, 2019;Liu et al, 2019). Therefore, in this study, a panel of 26 microsatellite markers was employed to evaluate the genetic diversity, population structure and phylogenetic relationship of the nine sheep populations.…”

Abstract. The objective of this study was to assess the genetic diversity and phylogenetic relationship of nine sheep populations, including two famous high prolific populations and seven popular mutton populations raised in China. Overall, these sheep populations in this study exhibited a rich genetic diversity. Both the expected heterozygosity and Nei's unbiased gene diversity ranged from 0.64 to 0.75, with the lowest value found in Dorset sheep (DST) and the highest in Hu sheep (HUS) and Ba Han sheep (BAS). The polymorphic information content (PIC) varied between 0.59 in DST and 0.71 in HUS and BAS. Specifically, for individual breeds, the small-tail Han sheep (STH) and the four introduced populations did not display the expected diversity; therefore more attention should be paid to the maintenance of diversity during management of these populations. The results of un-weighted pair-group method (UPGMA) phylogenetic tree and structure analysis indicated that the nine investigated populations can be divided into two groups. Suffolk (SUF) and DST were clustered in one group, and the other group can be further divided into three clusters: German Mutton Merino (GMM)–BAS–Bamei Mutton sheep (BAM), HUS–STH and Du Han (DOS)–Dorper (DOP). This clustering result is consistent with sheep breeding history. TreeMix analysis also hinted at the possible gene flow from GMM to SUF. Together, an in-depth view of genetic diversity and genetic relationship will have important implications for breed-specific management.

The present study aimed to systematically evaluate the genetic diversity of Chinese domestic duck breeds and ensure the most effective allocation and usage of conservation funds. We first performed an analysis of DNA genetic distance in 21 duck breeds by measuring short tandem repeats. Then, we calculated the extinction probability, contribution rate, and marginal diversity for each breed. The results showed that the extinction rate of the Zhongshan duck, Guangxi duck, and Ji’an duck were the highest at 0.67, 0.59, and 0.59, respectively, and that of the Linwu duck, Jinding duck, and Gaoyou duck were the lowest at 0.15, 0.18, and 0.19, respectively. The current diversity of populations was 7.72 and the expected diversity in five hundred years is 5.14 ± 1.15. The marginal diversity of the Chinese Muscovy duck was the largest (−2.20), accounting for 42.61% of the expected diversity, followed by the Guangxi duck (−0.49, 9.44%), whereas the Jinding duck was the smallest (−0.12; 2.32%). The protection potency of the Chinese Muscovy duck was the largest (0.61), followed by Guangxi duck (0.29), whereas the Jinding duck was the smallest (0.02). This study provides a reference for determining the conservation priority of Chinese domestic duck breeds or genetic resources.

“…The use of microsatellites had a special echo in the selection of sheep and goats to characterize certain breeds and determine their genetic distance. These studies are still relevant today (Liu et al, 2014;Zinovieva et al, 2015). In recent years, more than 50,000 SNPs have been tested to see their association with individual production traits.…”

“…Microsatellite markers could use to analyze genetic diversity in sheep breeds (Gaouar et al, 2012;Liu et al, 2014;Ebrahimi et al, 2017;Xia et al, 2021), goat (Bindu et al, 2012Hussain et al, 2013;Seilsuth et al, 2016;Asroush et al, 2018), and the other domestic animals (Petrovic et al, 2018).…”

Some aspects of DNA analysis in the selection of small ruminants

DNA analysis can have great practical application in the management and successful operation of the farm. The application of DNA technology is becoming a tremendous challenge for farm breeding of domestic animals. In recent years, traditional selection methods have been supplement by the results of molecular analysis of the genome. Determining the genetic distance of sheep and goat breeds had practical and multiple significance. Microsatellites are used widely in the selection, and genomic selection is becoming an increasing challenge for breeders. The development of SNP chips brings an immense advanced for rapid and comprehensive analysis of the genome, which is of great importance for the successful selection and Genomic selection in sheep concentrated on all aspects of genetic and production directions. However, it should be noted that genomic selections in sheep breeding, and especially in goat breeding, take place at a slower pace compared to cattle breeding.
