Magical gene / magical coat genes

Synort

The whole body under a running colour gradient, with a tobiano-shaped patch of the horse's own coat left in it, outlined in black - and white flecks through an otherwise untouched mane.

What it can come out as

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 5,000 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
`Syn/Syn`	Synort	0.001% — 1 in 100,000
`Syn/n`	Synort	0.019% — 1 in 5,263
`n/n`	Wild type	99.98%

The file

common/src/main/resources/horsegenetics/genes/synort.json — a data-driven gene, not a Java class. It is listed in the index.json beside it and registered by Genes' class initialiser at startup.

Key	`horsegenetics.synort`
Phase	magical — it adds signed colour in phase 3, after the pigment has resolved
Priority	106 — where it sits in the one `(priority, key)` paint order
Alleles	`Syn` · `n`
Varies per horse	3 values drawn once off the expressing allele copy, so a foal that inherits the copy inherits the look
Built from	AXIS, PARTS, PATCHES, RAMP, SPOTS, TOWARD

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.

Synort

The gradient is the whole horse: it starts cool over the head, neck and upper shoulder and travels the spectrum backward along the body, with no banding and nothing repeated. Laid into it is a tobiano-shaped region that keeps the horse's real coat colour, drawn round in a black outline so it reads as cut out rather than painted on. White markings sit over or under it as they like. The mane and tail keep their natural colour and carry a sprinkle of white spots; the hooves are black; and there is no regular mane striping.

the gradient over the whole body — PARTS, painted with RAMP
the tobiano patch, back to the horse's own colour — PATCHES, painted with RAMP
the black outline round it — PATCHES × PATCHES inverted, painted with TOWARD
white flecks through the mane and tail — SPOTS, painted with TOWARD
black hooves — AXIS, painted with TOWARD

Wild type

No synort.

Paints nothing.
