Piebald dragon

What a Piebald dragon looks like

Piebald is a recessive white morph, graded Mythic, well above the Rare a recessive morph usually gets.

White sits above colour, pattern and the element in a dragon's layers, so Piebald's patches cover whatever is underneath.

Nothing in the game today hides Piebald: a dragon with two copies always shows it.

How to breed a Piebald dragon

Piebald is recessive: a dragon shows it only with two copies of the gene, one from each parent. With one copy it looks Normal but carries Piebald hidden, a het, and passes it to half its babies.

What het means here: a baby that looks Normal from het × het carries Piebald 67% of the time, so the game labels it "67% het Piebald", a possible het. From het × Normal that is 50%, and every baby of a Piebald × Normal is a proven het. Hets and possible hets explains how those numbers move.

To prove a possible het, pair it with a Piebald. One Piebald baby proves it at once. Each Normal baby lowers the chance but never to zero: after three Normal babies in a row, a 67% het Piebald falls to 20%.

Where to get a Piebald dragon

Piebald turns up in crate dragons. In the pool of genes every crate draws from, the Piebald gene comes up at a rate of 6%; the Iron Crate turns that up 2.3 times and the Lava Crate 4 times. How often a crate dragon shows any morph at all depends on the crate: 8% in the Wooden Crate, 35% in the Iron Crate and 70% in the Lava Crate.

A crate dragon that doesn't show Piebald can still arrive with papers naming it as a gene it may carry hidden, at 20% to 60%. Breeding it is how you find out. What's in each crate has the rest of the odds.
