Magical gene / ground and strong white

Winged

Curved bands sweeping back from the withers along the ribs with ovoid spots between them, and one diagonal stripe across the shoulder - laid straight on the coat with one copy, and inside a dark saddle with two.

What it can come out as

Outcome	Carrying
Spot-Winged	`Wng/Wng`
White-Winged	`Wng/n`
Wild type	`n/n`

How each one is actually drawn - region by region, and the layers it is built from - is on the coding tab.

Finding one

About 1 in 1,250 wild horses is born showing this. That is the whole of the supply: catch one, or make one with the carrot below. Breeds set their own pools and a breed built around this gene will carry it far more often than the wild population does.

Wild pair	Shows as	How often
`Wng/Wng`	Spot-Winged	0.004% — 1 in 25,000
`Wng/n`	White-Winged	0.076% — 1 in 1,316
`n/n`	Wild type	99.92%

What it paints

Each outcome, described the way the gene file describes it, and then the layers that draw it in the order they are painted. The prose is the part a reader checks a bake against; the list underneath is what the engine actually did.

Spot-Winged

Two copies lay a dark field over the shoulder and barrel first - a saddle shape with a hard lobed boundary - and put the bands and spots inside it in white, at a much higher spot count. The bands often hook: one long band curving back on itself and ending broad.

the dark saddle over the shoulder and barrel — PATCHES × AXIS, painted with TOWARD
white arc bands through it — STROKES × AXIS, painted with TOWARD
white ovoid spots between the bands — SPOTS × AXIS, painted with TOWARD
bands reaching down onto the upper legs — STROKES × AXIS, painted with TOWARD

White-Winged

One copy puts the bands and spots straight onto the coat with no ground under them - two to five roughly concentric bands following the arc of the ribcage from the shoulder back toward the flank, tapering to points at both ends, with ovoid spots gathered near the band ends and over the shoulder, and a single diagonal band crossing the shoulder from the withers toward the elbow. White forms the core of each band and a desaturated tint runs alongside it. Every edge is hard.

the arc bands along the ribcage — STROKES, painted with TOWARD
the desaturated tint running beside them — STROKES, painted with TOWARD
ovoid spots between and beside the bands — SPOTS, painted with TOWARD
the diagonal band across the shoulder — STROKES × AXIS, painted with TOWARD
