The Chinese is an international breed of domestic goose, known by this name in Europe and in North America. Unlike the majority of goose breeds, it belongs to the knob geese, which derive from Anser cygnoides and are characterised by a prominent basal knob on the upper side of the bill. It originates in China, where there are more than twenty ...
The Chinese and African Geese are the domestic breeds of the swan goose (A. cygnoides); they can be recognized by their prominent bill knob. [ 1 ] Some breeds, like the Obroshin Goose and Steinbach Fighting Goose , originated in hybrids between these species (the hybrid males are usually fertile – see Haldane's Rule ).
The knob-billed duck (Sarkidiornis melanotos) or African comb duck is a type of duck found along the tropical/sub-tropical wetlands and waterways of Sub-Saharan Africa and the island of Madagascar, as well as most of South Asia and mainland Indochina. Most taxonomic authorities classify the knob-billed duck and the comb duck separately.
The African Goose is one of two domestic goose breeds that derive from the wild species Anser cygnoides, the other being the Chinese, to which it is closely related. [9]: 364 [3] Domestication took place in north Asia, and birds of this type were later brought to Europe, possibly via Madagascar; [10] they were present in Britain before the end of the seventeenth century.
A domestic goose is a goose that humans have domesticated and kept for their meat, eggs, or down feathers, or as companion animals. Domestic geese have been derived through selective breeding from the wild greylag goose ( Anser anser domesticus ) and swan goose ( Anser cygnoides domesticus ).
The indication of knobs at the base of a goose's bill is viewed negatively and is considered indicative of inbreeding. Likewise, Pomeranian Geese with such undesirable traits as dark feathers in the wings, dewlaps, excessively white heads, orange bills, orange feet, and undersized bodies should be avoided as breeding stock.

The close-up of head. The swan goose is large and long-necked for its genus, wild birds being 81–94 cm (32–37 in) long (the longest Anser goose) and weighing 2.8–3.5 kg (6.2–7.7 lb) or more (the second-heaviest Anser, after the greylag goose, A. anser). The sexes are similar, although the male is larger, with a proportionally longer ...
