Cross 12

Purpose: The second of the intercross phase where I am crossing the separate lines that have formed from the individual backcrosses. This cross is intended to try and stabilize the snow white phenotype using a male and female that both seem to express snow white. It was also set up to probe into the larger fin genetics of the male. This pair was introduced to each other on June 23rd, 2024.

Male (C5BM):

  • Gandalf’s son/grandson from Cross 5.

  • Strain: Technically 3/4 Snow White but phenotypically a full Snow White

  • Relevant genes. Some are assumptions, indicated with italics:

    • Base body color: Blond (bb)

    • Magenta: MM or Mm (larger tails suggests potentially heterozygous)

    • European Blau: (rr)

    • Stoerzbach: (ss)

Female (C7AF):

  • Gandalf’s daughter/granddaughter from Cross 5.

  • Strain: 3/4 Snow-White

  • Relevant genes. Some are assumptions, indicated with italics. Although their decedents strongly support the claims:

    • Base body color: Blond (bb)

    • Magenta: likely homozygous (MM) but could be het (Mm)

    • European Blau: (rr)

    • Stoerzbach: (ss)

This cross failed as it never produced any fry. This suggested that Gandalf is now too old to reproduce and I retired him from the breeding project.
