Lineage review · Batch 029: Exterior-light stock use explicitly reported, but exact original pairing and genetic ratios are NOT documented. Original specialist/breeder source ↗
Lineage review · Batch 018: Original parental mating not documented sufficiently for a defensible pedigree; the illustrated ancestry gap stays disconnected. Specialist record ↗
Overview
Ono's nontransparent-scale white-and-vermilion red-white ornamental selection known as Komachi. The evidence below is based on a documented specialist variety entry, not independently verified laboratory genetics.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| The specialist variety catalogue identifies Kunio Ono / 小野久仁雄 as the original maker for the 2018 record. | Documented specialty-catalogue attribution, not independently authenticated creator correspondence | K185 ↗ |
| Clear white and vermilion body-color patches without the diagnostic transparent-scale appearance. | Source-defined phenotype and classification, not DNA genotype | K185 ↗ |
| The 2018 specialist origin record attributes the Komachi nickname to Ono; specific individual founding crosses are not described as verified. | Specialist historical selection summary; precise broodstock not verified | K185 ↗ |
| Komachi is not an alias for the older transparent-scale Sarasa red-white variety or all nontransparent kohaku specimens. | Differentiation from another historical name or pedigree limitation | K185 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- No independently inspected original breeder register, genotype assay or complete individual parent-fish mating ledger is available.
- Source attribution and the historical year should not be interpreted as confirmed first retail sale date or authentication of present-day fish.
- External catalogue images are not republished without separately verified copyright/reuse permission.
