Selection scan statistics reveal a putative selective sweep unique to the Straight Egyptian subgroup on ECA 18. (A) H, H12, and reflected Tajima’s D statistics were all scaled to 0 – 1. 99th percentile threshold values are plotted as dashed horizontal lines for each statistic. The vertical gray region indicates the genomic region encompassing all 6 peaks observed for the Straight Egyptian group. Colored asterisks indicate which test statistics had peaks exceeding the indicated threshold within the region of interest. (B) Representative profile of a Straight Egyptian Arabian Horse and (C) of an Arabian horse used for Racing and with no Straight Egyptian ancestry.
