Separate appearance from explanation
A visible color or pattern is an observation. Assigning a genetic cause requires more evidence than a photograph or a seller’s grade label.
Lighting, background, age, stress, and camera processing can alter how the shrimp looks. Record these conditions when comparing animals.
Follow groups across generations
Track parent groups and offspring over time if you are selecting a trait. Keep uncertain parentage explicit in a shared colony.
A large batch may show variation even when the parents look similar. A single result does not establish a guaranteed inheritance pattern.
Describe your evidence carefully
Say what you observed and how many groups or generations you followed. Do not use scientific language to overstate a hobby observation.
For formal genetic claims, seek qualified sources and methods. A breeding log helps organize experience but does not replace controlled research.
