“…The 15 autosomal microsatellite markers we applied have been in widespread use since they were recommended for diversity studies by ISAG‐FAO and the International Society for Animal Genetics (Cothran & Luís, 2005; FAO, 2011). Despite the advance of SNP genotyping, very few studies of horses have used SNPs to date for phylogenetic questions (Petersen et al, 2013) and the use of use of 12 to 17 microsatellites for breed analysis remains popular (e.g., Cosenza, La Rosa, Rosati, & Chiofalo, 2019; Isakova et al, 2019; Khanshour, Hempsey, Juras, & Cothran, 2019; Khaudov et al, 2019; Ustyantseva, Khrabrova, Abramova, & Ryabova, 2019; Zeng et al, 2019). The dendrogram of breed relationships analyzed by SNP typing of 36 breeds (Petersen et al, 2013) is almost an exact match of the results from the 15 microsatellite loci, thus suggesting that the results from our 15 microsatellites are robust.…”

STRUCTURE remains the most applied software aimed at recovering the true, but unknown, population structure from microsatellite or other genetic markers. About 30% of STRUCTURE-based studies could not be reproduced (Molecular Ecology, 21, 2012, 4925). Here we use a large set of data from 2,323 horses from 93 domestic breeds plus the Przewalski horse, typed at 15 microsatellites, to evaluate how program settings impact the estimation of the optimal number of population clusters K opt that best describe the observed data. Domestic horses are suited as a test case as there is extensive background knowledge on the history of many breeds and extensive phylogenetic analyses. Different methods based on different genetic assumptions and statistical procedures (DAPC, FLOCK, PCoA, and STRUCTURE with different run scenarios) all revealed general, broad-scale breed relationships that S U PP O RTI N G I N FO R M ATI O N Additional supporting information may be found online in the Supporting Information section.

“…Among the most informative methods of analyzing the allel-fund of horses of world breeds, modern publications consider the following: genome-wide and targeted genome sequencing on the Illumina platform [6][7][8], the use of SNP chips [9], microsatellite analysis [10][11][12][13][14][15], sequencing of the D-loop of mitochondrial DNA [16], Y-chromosome analysis [17][18][19].…”

The purpose of the study was to study the dynamics of the main selected traits in horses of the New Altai breed and the genetic characteristics of the breed. In this paper, the indicators of the main measurements of the body and live weight of horses, depending on gender and region of birth, are analyzed. The main genetic and population parameters of the breed were calculated based on microsatellite DNA loci: the total number of alleles at 17 loci (Na), the average number of alleles per locus (Nv), the level of polymorphism (Ae), observed (Ho) and expected (He) heterozygosity, coefficients of intrapopulation inbreeding (Fis), genetic similarity (RXY) and genetic distances (DXY). It has been established that the horses of the New Altai breed are characterized by a relatively high level of polymorphism and genetic diversity, both in the breed as a whole and in the context of breeding regions. The high genetic similarity of the New Altai breed with the Russian Heavy Draft and Altai breeds has been revealed. The study of the genetic structure of the breed, the levels of its intra- and inter-population diversity in combination with classical zootechnical assessment methods showed the consistency of the chosen cultivation strategy of the New Altai breed.
