Description
Homozygous (am//am) pigeons are missing the tips of some or all of their toes. Occasionally also wing tips are missing and a "hook beak" my be present. Heterozygotes (am//+) appear normal.
Inheritance
Amputated is an autosomal recessive mutation. This means that both parents need to carry the mutant gene for it to express in the next generation. As a recessive mutation, it is possible for this mutation to be carried by a bird who does not visually express it.
History
This mutation was first identified in squabbing King pigeons in 1945 and investigated by WF Hollander.
