Which feature distinctly identifies the male pronghorn?

The large black jaw patch is a distinctive feature that helps identify male pronghorns. This characteristic is prominent and visually striking, making it easy to differentiate males from females. While female pronghorns may have some dark markings, the black jaw patch is typically larger and more pronounced in males, serving as an important visual cue during mating displays and territorial behaviors.

The large white belly is more of a general feature of pronghorns and does not specifically distinguish males from females. Both genders can exhibit similar body characteristics, including coloration on the belly. Long legs for speed are a characteristic of pronghorns in general and do not specifically point to male pronghorns, as both sexes are adapted for speed. The curved horn shape is also present in both males and females, although males do have longer horns. However, the distinguishing factor emphasized in this context is the large black jaw patch, making it the correct identification feature for male pronghorns.
