![]() ![]() In western countries there are many colour varieties of the Japanese Bantam. Long-legged birds bred to each other can not produce short-legged offspring. : 142 This trait is caused by the creeper gene, Cp, which displays the standard behaviour of recessive lethal alleles: when short-legged birds are bred, 25% of the embryos are homozygous for the lethal allele, and die in shell 50% are heterozygous, and develop into short-legged birds the remaining 25% are homozygous for the non-lethal allele, and develop longer legs, making them unsuitable for showing. In 1937 an international breed club – the International Chabo Bantam Club – was formed at a meeting in Switzerland. : 174 : 252 A breed society, the Japanese Bantam Club, was formed during the Crystal Palace Poultry Show of 1912. : 172 The Japanese Bantam apparently reached the United Kingdom in the 1860s it was not included in the first British poultry standard of William Tegetmeier in 1865, but was described in his The Poultry Book in 1867. : 171 The first documented exports of the Chabo to Europe and the United States began at about this time. Japan was effectively closed to all foreign trade from 1636 until about the time of the Meiji Restoration in 1868. : 20 The earliest recognisable depiction of a Chabo in Japanese art dates from the beginning of the seventeenth century a short-legged chicken with tall upright tail shown in the Portrait of Jacoba Maria van Wassenaer by Jan Steen, painted in about 1660, is believed to be a Chabo. Mitochondrial DNA evidence suggests that it, and all other Japanese breeds of ornamental chicken, derived through selective breeding from fighting chickens, the ancestors of the modern Shamo breeds. ![]()
