What physical characteristic is the most consistent marker of a zonkey's zebra heritage?

Answer

Striping pattern inherited from the zebra, most strongly visible on the legs

The most unmistakable feature inherited from the zebra parent is the striping pattern. However, it is uncommon for a zonkey to be completely covered in stripes like a purebred zebra. Instead, the striping manifests most distinctly and consistently on the animal's legs. This leg striping provides a striking visual contrast against a body coat that often defaults to a solid color, such as gray or dun, mirroring the coloration frequently seen in donkeys. While faint stripes may occasionally appear elsewhere, such as the hindquarters, neck, or shoulders, the leg striping is the defining and most reliable indicator of zebra ancestry.
