Caridina crossing evidence archive

Scope

12 dated sources, including public breeder interviews, first-person forum F1/F2 reports and trade pattern classifications. All 12 lack a published controlled offspring census and molecular locus identification. Some contain qualitative outcomes only.

F1 and F2: correctly defined

F1 denotes offspring of the chosen parental generation P. F2 normally denotes offspring produced by crossing F1 individuals, not automatically any second mating, unrelated outside stock, or repeated backcross to P. State backcross pedigree explicitly rather than calling it F2 without qualification.

No universal 25% or 80% predictions

The often repeated 25% Taiwan Bee F2 expression and 80% Galaxy breeding-true claims cannot be applied broadly without specified parental genotypes, observed family sizes, penetrance, viability and verified stock lineage.
