Orange ghost question

Edit: Looks like people beat me to it while I was typing. I'll just leave it up anyways LOL.

I would find a combo that is het orange ghost or visually orange ghost to breed to your orange ghost.

For the percentages:

Spider 50% het orange ghost: one of this girl's parents was 100% het orange ghost. When bred to a non-het, you have the potential to produce hets and non-hets.
Let's say the pairing was a spider 100% het orange ghost to a normal.

You would produce
spiders 100% het ghost (1:4)
normals 100% het ghost (1:4)
spiders (1:4)
normals (1:4).

Those probabilities are per egg. Per egg, you have a 2:4 (or 1:2) chance of the baby being het ghost, hence the 50% het orange ghost.

Spider 66% het orange ghost: both parents were 100% het orange ghost. Let's say the pairing was a spider 100% het orange ghost to a normal 100% het orange ghost.

Keeping in mind the probabilities are on a per egg basis, you have the potential to produce
spider ghosts (1:8)
ghosts (1:8)
spiders 100% het ghost (2:8)
normals 100% het ghost (2:8)
spiders (1:8)
normals (1:8)

Let's say the animal in the egg is not a visual ghost. That leaves you with 6 possibilities of what you may have, so the probabilities for that one egg change to
spiders 100% het ghost (2:6)
normals 100% het ghost (2:6)
spiders (1:6)
normals (1:6)

This means that there is a 4 out of 6 chance (or 66%) that the animal you are looking at is het ghost.

I hope that helps.
