Lineage review · Batch 024: Breeder or specialist records establish the pictured historical population, selected form or source stock. Dashed arrows do not imply DNA-confirmed parents or dominance. Original breeder/specialist source ↗

Lineage review · Batch 20: At this earlier review, no defensible original breeding cross was established. A later Batch 024 review documented source-stock or selection history; see that updated note above. Individual founder parentage remains unverified. Original specialist source ↗

Overview

A selected Medaka combining Swallow fin-ray extension and Meller split-fin traits. Historical catalog creator attribution: Yukio Oba / 大場幸雄 (Hiroshima). The 2017 historical variety group is a documentary context, not proof of the first sale.

Known research gaps

  • Precise commercial introduction dates, actual founder specimen IDs and complete generation-by-generation records are not fully documented in this catalog.
  • The named phenotype or historical breeding description is not a DNA-verified pedigree or a guaranteed inheritance ratio.
  • Current breeder-authenticated stock, precise strain-specific water parameters and photograph licensing remain unconfirmed.
