Bone Horns dragon

What a Bone Horns dragon looks like

Bone Horns is a recessive accent morph, graded Rare like every recessive morph, since it takes two copies to show.

Accent genes add something of their own without moving the main markings, so Bone Horns stacks with every other gene.

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

With Regal on the same dragon, Regal's gold wins over the ivory.

How to breed a Bone Horns dragon

Bone Horns 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 Bone Horns hidden, a het, and passes it to half its babies.

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

To prove a possible het, pair it with a Bone Horns. One Bone Horns 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 Bone Horns falls to 20%.

Where to get a Bone Horns dragon

Bone Horns turns up in crate dragons. In the pool of genes every crate draws from, the Bone Horns gene comes up at a rate of 4%, tied for the lowest of any gene there; 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 Bone Horns 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.
