Abstract

<abstract abstract-type="main" id="age12214-abs-0001"> <title>Summary</title> <p>Variation in two SNPs and one microsatellite on the Y chromosome was analyzed in a total of 663 rams representing 59 breeds from a large geographic range in northern Eurasia. SNP<italic>A‐oY1</italic> showed the highest allele frequency (91.55%) across the breeds, whereas SNP<italic>G‐oY1</italic> was present in only 56 samples. Combined genotypes established seven haplotypes (<italic>H4, H5, H6, H7, H8, H12</italic> and <italic>H19</italic>). <italic>H6</italic> dominated in northern Eurasia, and <italic>H8</italic> showed the second‐highest frequency. <italic>H4</italic>, which had been earlier reported to be absent in European breeds, was detected in one European breed (Swiniarka), whereas <italic>H7</italic>, which had been previously identified to be unique to European breeds, was present in two Chinese breeds (Ninglang Black and Large‐tailed Han), one Buryatian (Transbaikal Finewool) and two Russian breeds (North Caucasus Mutton‐Wool and Kuibyshev). <italic>H12</italic>, which had been detected only in Turkish breeds, was also found in Chinese breeds in this work. An overall low level of haplotype diversity (median <italic>h</italic> = 0.1288) was observed across the breeds with relatively higher median values in breeds from the regions neighboring the Near Eastern domestication center of sheep. <italic>H6</italic> is the dominant haplotype in northwestern and eastern China, in which the haplotype distribution could be explained by the historical translocations of the <italic>H4</italic> and <italic>H8</italic> Y chromosomes to China via the Mongol invasions followed by expansions to northwestern and eastern China. Our findings extend previous results of sheep Y chromosomal genetic variability and indicate probably recent paternal gene flows between sheep breeds from distinct major geographic regions.</p> </abstract>
