The genetics causing pangaré have not yet been found. It appears in many draft horses and ponies, but is far rarer in sport horses. Donkeys also show the mealy affect, but that may be due to a completely different (set of) gene(s).
It is not clear whether pangaré is caused by one gene or more, and whether it is completely recessive or dominant. Pangaré is often called mealy because of its mealy effects on the horse’s coat. Generally it lightens the area above the muzzle, the flanks and belly, but it can lighten the entire coat as well. Perhaps it originated once as a camouflaging technique.
In the game Pangaré is inherited simply as one dominant gene. As the genetics for pangaré are still unknown, and there is no test available for it in real life, we have decided to keep the pangaré genetics hidden and untestable. It is not considered an important colour in the game.
