Abstract. Animal breeding hobbyists have been useful to science because they identify and isolate color
coat mutations that geneticists can in turn use in their studies of the development and differentiation of
color cells. This paper discusses a very interesting color mutant, the Japanese Galaxy, tracing its creation
from back to a self-educated genetics hobbyist, Hoskiki Tsutsui. The paper discusses a constituent gene
previously studied by Dr. Violet Phang, the snakeskin gene (the linked body and fin genes Ssb and Sst).
And it discusses a gene previously unknown to science, the Schimmelpfennig Platinum gene (Sc).
Through crossing experiments, the author determines that the combination of these two genes produces
an intermediate phenotype, the Medusa. Incorporating the Grass (Gr, another gene unknown to science)
gene into the Medusa through a crossover produces the Galaxy phenotype. Microscope studies of the
snakeskin pattern in Galaxies and snakeskins reveals some parallels with similar studies made of the
Zebrafish Danio.
Key Words: Galaxy Guppy, snakeskin, Schimmlepfennig, Medusa, Zebrafish.
