Biology:Rumpless chickens
Rumpless chickens are characterised by caudal dysplasia, the absence of the pygostyle or caudal appendage – the "parson's nose". This is the result of inheritance of an autosomal dominant trait. The mutation which causes it is unknown; two candidates have been proposed.[1]: 10
History

Rumplessness in chickens has been documented for centuries. An early description is that of the Bolognese ornithologist Ulisse Aldrovandi in his Ornithologiae Tomus Alter of 1600.[2]: 127 [3]: 318
Rumpless breeds
Rumpless breeds of chicken include: the Araucana or Rumpless Araucana of South America, both large fowl and bantam;[4]: 45 in Europe, the Belgian Barbu de Boitsfort, Barbu de Grubbe and Barbu d'Everberg bantams,[4]: 75 the German Ruhlaer Zwerg-Kaulhühner or Rumpless Booted Bantam[4]: 92 and the Rumpless Game of the United Kingdom (both large fowl and bantam), sometimes called the Manx Rumpy or Persian Rumpless;[4]: 272 [5]: 65 and in Asia, the Japanese Uzurao, a rumpless equivalent of the Tosa-Kojidori bantam,[6]: 95 and Ingie (large fowl) from Kagoshima Prefecture,[6]: 103 and the Piao of Yunnan Province in China.[7]: 787
