Table 1 summarizes the SNPs analyzed in this study. The total genome length was 2,534.98–2,535.30 Mb, with the shortest Bos taurus autosomal chromosome (BTA) being 42.72 Mb (BTA25) and the longest 158.09Mb (BTA1). The distribution of SNPs varied among the chromosomes, with BTA1 having the highest number of SNPs (2026–2176) and BTA28 having the fewest (580–607); the longest SNP interval was identified on BTA20 (38.77 Mb). However, average SNP intervals were relatively consistent among the chromosomes, and the overall average distance between two adjacent SNPs was 70 kb.
