Where on the Zonkey's body are the inherited black stripes most characteristically pronounced and concentrated?

On the legs and the underside or belly

The manifestation of the zebra's iconic striping pattern on a Zonkey is rarely comprehensive; instead, it is often patchy and concentrated in specific regions. The black stripes inherited from the zebra are most distinctly observed and concentrated upon the legs of the hybrid. Furthermore, the stripes are highly visible on the lighter-colored areas of the body, specifically the underside or belly region. While some Zonkeys might show striping across the neck or torso, this coverage is typically sparse and less defined compared to the strong markings found low on the limbs and abdomen. The base coat color itself usually mirrors the donkey, being a solid tan, brown, or gray, against which the black stripes stand out most clearly in those key areas.
