White from coronet to and including the pastern is known as a ____ leg marking.

The marking that extends from the coronet band down to and including the pastern is referred to as a pastern leg marking. This type of marking is typically characterized by a white area that covers the lower part of the leg, specifically the pastern, which is the area just above the hoof and below the fetlock joint.

Understanding the terminology used to describe horse markings is essential for horse evaluation, as these markings can play a role in identifying horses, assessing their breed standards, and even in judging competitions. The pastern marking specifically allows evaluators to accurately convey details about a horse's appearance, which can influence both aesthetics and potential breeding decisions.

In contrast, other options do not accurately represent the area in question. Ankle refers to a different location on the leg, while half stocking and full stocking markings extend higher up on the leg, typically covering more prominent areas like the fetlock or even beyond, which is not applicable to the description given in this case.
