Medaka breeder-documented selection lineEvidence by claimIndependent review ongoing

Savanna describes an Off White line from (White Diamond × Fromage) × White Diamond RLF.

Overview

The breeder's objective includes yellowish body expression, vivid fin patterns, and denser network-like markings. The catalog is a first-party account, not independent genetic confirmation.

Breeder-reported lineage and selection

The dashed arrows map reported inputs, not independently authenticated parent pairs. Multi-stage inputs are shown together for readability; this is not a verified single-generation mating plan.

Dashed connectors show breeder-reported input or selection history; they do not prove actual parent pairs, alleles, or dominance. Parent fish IDs are not independently established.

Known research gaps

  • A verified first-publication or first-sale date has not been established.
  • Related Snow White shares some inputs, but the breeder describes distinct selection objectives.
  • No independent DNA-verified inheritance, controlled water-parameter optimum, graded phenotype guarantee or offspring ratio is established.
  • Third-party catalog photos are not licensed for republication in this entry.
