Picture-style published research pedigree
F0 founder cross
At Qian Hu Fish Farm in Singapore, experimental F1 hybrid broodfish traced to crosses between Red Grade 1 and Malaysian Golden founder varieties. The study did not establish which named strain acted as sire or dam for every sampled fish.
F1 experimental pairings
Researchers describe establishing two mapping families by pairing two sets of F1 hybrid broodfish. The published record supports F1 × F1 within research mapping families; it does not document an exclusive commercially sold line of Super Red or Crossback offspring.
F2 genotyping cohort
A later RAD-sequencing study mapped 94 F2 offspring and their parents from one family; genome analysis organized selected SNPs into 25 linkage groups. A family map is not a deterministic trait or dominance table.
Limit of the pedigree
The founders are identified by red and golden variety labels, not a named exported breeding strain or complete public microchip record. No assertion about which color form dominates F1 or F2 is justified from this source.
