Three colour strains are not trade-line genotypes
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The genetics and colour evidence boundary now preserves the full methods behind the 2026 red, yellow and blue pigment-pathway comparison, including its unresolved animals, pools, tanks, source identities and phenotype measurements.
Why it changed
The study reported three biological samples per endpoint but not the shrimp count or pooling behind them, culture-tank replication or strain allocation. It compared transcripts, normalized western-blot bands and relative fluorescence without gene manipulation, crosses, standardized colorimetry, pigment-compound identification or named-trade-line validation.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
