Magical gene / fields and regions

Oscar

Black laid over the whole horse and then flaked away in big wavy upright stripes, so the coat underneath shows through the gaps like the scales of a fish.

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.

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.

Oscar

A very heavy sooty that turns the coat black from head to toe, and it does it on anything - single cream, double cream, pearl, champagne, none of them stop it. Then the black flakes: large wavy stripes lift away and reveal the horse's real genetic colour underneath, whatever that is, and they run mostly upright rather than along the body. At its quietest that is a black horse with a little colour showing on the neck; at its loudest it is half and half, with flecks of dark in the colour and flecks of colour in the dark. Mane and tail follow whatever the flaking does where they meet it. It sits under every white marking. One copy looks exactly like two.

  1. black over everything — PARTS, painted with TOWARD
  2. the flakes lifting away again — STROKES, painted with TOWARD
  3. dark specks left in the flaked areas — SPECKLE × STROKES, painted with TOWARD

Wild type

No flaking.

Paints nothing.
