Overview
The 2008 specialist catalog credits this vivid-red transparent-scale development to 小宮正城. The archive links vermilion Youkihi pigment to a transparent-scale breeding direction with visually variable patterns. Creator-versus-discoverer status is source-scoped.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Historical record: Masaki Komiya / 小宮正城 (romanization provisional) — Original discoverer historically credited. | Archive maker or discoverer attribution | E78 ↗ |
| The archive links vermilion Youkihi pigment to a transparent-scale breeding direction with visually variable patterns. | Source-described historical breeding and development, not independently genotyped | E78 ↗ |
| Red-orange body patches, sometimes concentrated near the head or distributed irregularly. | Visual phenotype only; individual expression can vary | E78 ↗ |
| Separate later transparent-scale Nishiki/Sarasa/Tancho identities have their own histories and should not be used as aliases for this foundation. Historical context: 2008 historical catalog section. | Editorial distinction grounded in cited source; exact sale dates not guaranteed | E78 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- The exact maternal/paternal transparent-scale stock and inheritance model are not verified.
- Cited first-generation and selected-parent statements do not prove DNA genotype, inheritance rate or present-day breeder-stock identity.
- No third-party breeder/catalogue image is reproduced; photo rights and original genetic records require independent review.
