Historical Medaka research entryEvidence by claimIndependent review ongoing

JOURAKUAN's own Deep White page describes repeated selection for stronger white pigment-cell expression from Reiwa Aurora Sapphire-related source stock.

Overview

The breeder frames white pigment-cell expression as a selection objective and calls the program continuing development. This is an original breeder account, not a laboratory pigment-cell study or fixed cross. Historical creator/source attribution: JOURAKUAN / 静楽庵.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.

Known research gaps

  • White pigment-cell speculation does not establish an allele or specific inheritance ratio.
  • Deep White is not synonymous with the historic 2014 White-spotted Lame Miyuki.
  • 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.
