In an aim to deal with the origin of the gold-fish, the chromosomes of fifteen varieties of the gold-fish are investigated in comparison with those of Funa subspecies according to the C-banding technique. The varieties excepting the Shubunkin and the Comet are characterized by the second largest submetacentrics chromosomes as markers carrying C-bands on their short arms, being two in the female and one in the male. The same feature is observed in the Kinbuna, a variety of Funa (C. a. subsp.). This seems to be an important picture for the assessment of the ancestor of the gold-fish.,
We are very indebted to Dr. Sajiro Makino, M. J. A., Professor Emeritus, Hokkaido University, for improvement of the manuscript and revision of data.
