Breeder knowledge
A practical distinction
A morph is usually a recognisable inherited form, such as Hypo, Translucent, Zero or Witblits. A trait may describe a particular inherited feature, while a colour line is developed by selecting for appearance across generations and may involve many genes rather than one simple mutation.
Red, orange, yellow, tiger and dark projects are commonly discussed as lines or visual selections. The words can describe appearance and breeding history without identifying a single known gene.
Evidence limit
Why labels are not enough
Commercial morph terminology has largely developed through breeder records and repeated pairings rather than peer-reviewed genetic mapping. A label can be useful, but it does not replace a clear account of the parents, known hets and the result of previous pairings.
Good breeding information separates what is visually apparent, what is genetically demonstrated and what is only suspected.
