Picture gene & lineage tree
Visual pedigree of breeder-reported inputs, where available. Dashed arrows represent documentary claims or selection history, not DNA-tested genes.
Source explicitly credits family and lame selection; named original sire/dam unreported Source: Medaka no Yakata archival 2015 credited JOURAKUAN variety record

Lineage recheck · Batch 025: Original breeder/archival account describes this stock origin or multigeneration selection. Dashed connectors document history, not DNA or individual fish parents. Source evidence ↗
Lineage review · Batch 017: The review has not established a defensible original breeding pair. The picture ancestry node remains deliberately disconnected. Specialist source ↗
Overview
The public historical entry is concise: it provides creator and phenotype but not a complete genetic cross tree. This article intentionally does not invent the missing ancestry. Historical creator/source attribution: JOURAKUAN / 静楽庵.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Medaka no Yakata's 2015 catalog group credits JOURAKUAN | Historical creator evidence | H89 ↗ |
| The catalog describes reflective lame introduced or selected into a clear-brown body line | Recorded phenotype selection description | H89 ↗ |
| It does not identify an exact pair of named founder cultivars for the line | Crossing details undisclosed | H89 ↗ |
| The archival record is not evidence that identical verified parent-stock fish remain commercially available now | Authentication and date limitation | H89 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Need breeder's original cross ledger or dated first-release notice before filling ancestry.
- Do not reclassify every clear-brown lame marketed variant as the same selected breeding line.
- DNA-verified ancestry, independent inheritance ratios and authenticated present-day stock provenance require further source review.
- No third-party photographs are rehosted without documented permission.
