Runs of homozygosity reveal signatures of positive selection for reproduction traits in breed and non-breed horses

Table 2 Summary of runs of homozygosity (ROHs) detected in whole genome sequencing data of ten horses

	Horse 1	Horse 2	Horse 3	Horse 4	Horse 5	Horse 6	Horse 7	Horse 8	Horse 9	Horse 10
	Dülmen	Sorraia	Sorraia	Hanoverian	Hanoverian	Hanoverian	Hanoverian	Saxon-Thuringian Heavy Warmblood	Arabian	Thoroughbred (SRR1055837)
Number of ROHs (50)	2804	4395	3955	2965	3214	3104	3167	3138	3581	4595
Number of private ROHs (50)	722	1578	1349	538	752	662	709	739	934	1940
Number of ROHs (500)	188	541	422	145	202	179	175	211	259	599
Number of private ROHs (500)	152	352	285	80	150	84	109	123	153	459

The number of ROHs in windows of a minimum amount of 50 homozygous SNPs and 500 homozygous SNPs are shown. All ROHs were compared in-between horses and filtered for private ROH regions that could only be found in one horse
50 = A minimum amount of 50 homozygous SNPs
500 = A minimum amount of 500 homozygous SNPs
