Not exactly true. Most people that are into genetics agree that there are two different genes that cause appy patterns - LP and PATN. Some theorise that there are two different PATNs, PATN1 and PATN2, but I don't know enough about appies to go that far lol. Basically, LP causes spots, PATN causes white. So this horse has one copy of LP - causing the spots, but only one, as two copies make no spots again (confusing, I know lol). He also has one copy of PATN I think - a small white blanket, but with two copies you would expect more white, as in a leopard.
Please remember appies are not my forte lol. ND or Face could give more info than me, should they happen upon this.
OP - I would call him a black spotted blanket with varnish roan. A mouthful, but seems fairly accurate looking at him.
