Donkey PAB. (A) Schematic drawing of the location of donkey PAB-X at 1,887,889 bp flanked by LINE L1 elements; (B) Alignment (in IGV⁶⁸) of male donkey long reads (horizontal lines) to a ~ 6 kb region (demarcated by black vertical arrows) around PAB-X showing the start (left arrow) of drop in read coverage, reaching to 50% (right arrow) in the end; 10 male reads that are denoted with orange horizontal arrows are likely from the donkey Y chromosome because they drop off from the X chromosome at the same sequence position.
