Shubunkin of age, even though they live much longer. Blue colouring in goldfish comes from black pigment within the body wall. It will not show as blue in fish with metallic type scales, but will look blue if the fish has matte or nacreous scales. The nacreous (formerly called calico) scale type is produced in a fish that carries the gene for metallic scales, as well as the gene for matte scales (the fish is heterozygous). Only nacreous scales are accepted by the Shubunkin breed standards. Shubunkin The Shubunkin was created by Yoshigoro Akiyama （, by crossing Calico telescope eye with
A New Kind of Science of traffic, material fracture, crystal growth, biological growth, and various sociological, geological, and ecological phenomena. Another feature of simple programs is that, according to the book, making them more complicated seems to have little effect on their overall complexity. "A New Kind of Science" argues that this is evidence that simple programs are enough to capture the essence of almost any complex system. In order to study simple rules and their often complex behaviour, Wolfram argues that it is necessary to systematically explore all of these computational systems and document what they do. He further argues that this study should
