Goose breeds are usually grouped into three weight classes: Heavy, Medium and Light. Most domestic geese are descended from the greylag goose ( Anser anser ). The Chinese and African Geese are the domestic breeds of the swan goose ( A. cygnoides ); they can be recognized by their prominent bill knob.
