Ok, so I have been kicking around the though of jumping into breeding in the next year or so, and started looking at different combinations of morphs. I have a Pastel Het. Pied male(I think....he has been probed twice one time he was male the next female...I didn't do the probing) And I would love to bread to a Butter Het. Pied.

I am having two problems, first a Butter Het. Pied is proving to be hard to find. So I have resigned my self to starting with a standard Butter and moving on from there.

This brings me to my second problem and the real question. When you cross a Pastel Het. Pied with a butter you end up with something like this:
Percent Fraction Morph
12.5% 1/8 Normal
12.5% 1/8 Butter
12.5% 1/8 Pastel
12.5% 1/8 Butter Pastel
12.5% 1/8 Het. Piebald
12.5% 1/8 Butter Het. Piebald
12.5% 1/8 Pastel Het. Piebald
12.5% 1/8 Butter Pastel Het. Piebald

My question is, how do you tell which are het. and which are not? I have heard of the "tracks" and while my pastel has them I am still not a firm believer in them as a marker.
