Question about morph "standards"

[Gerardo]

I am trying to figure out a good way to explain this without giving a lecture on histone methylation and Mendelian genetics , so bear with me.

For a specimen to be considered a "morph", in the context of a trait that is directly heritable via a co-dom or recessive gene, then there must a constant trend in how that population of morphs develop. For example, every albino ball python I know of has yellow and white in place of the normal black and brown, the pattern itself is relatively unaffected though; albinism is also proven out to be recessive so I can say with relative certainty that an albino bred to a normal will produce normal babies that carry the albinism gene and that an albino bred to a normal het albino will likely yield a mixture of albino and normal 100% het albino. Of course, this is a very cut and dry example, some morphs are a bit more complicated, ex. Granite back and Anthrax retics. There are a few trends, but they are a lot more unpredictable. In addition to this, we must think population wise when we determine these trends as individuals will differ at least slightly no matter how close they are. Hope that helps, it's a rough example but it should you start you off.

It does help out but i wanted to know at what point does an animal go from being a really light/dark normal to being an actual morph. How can you visually identify the morph. Not tryin to give anybody a hard time but there is not a whole lot of info i could find on traits a morph MUST have to be considered a specific morph and what traits it CANT have. Best way to compare what im saying is dog breed standards.
