Markings

Markings come from two genes, Leopard (L) and Pinto (P). Both are dominant, so one copy is enough.

Genes	Marking
Neither	No markings
Leopard only	Dots. Either black dots or white dots
Pinto only	A white marking. Either a plain white pattern or a whitefield
Leopard and Pinto	Whitefield

When a horse could show one of two looks, the game picks between them at random.

Planning a spotted foal#

Because both genes are dominant, a horse with nL or LL will always show spots. A foal only gets a Leopard gene if at least one parent passes it on, so if neither parent carries L, a spotted foal cannot appear.
