OMIA 001731-8932 : Tail feathers, number of in Columba livia

In other species: chicken , California condor

Mendelian trait/disorder: unknown

Considered a defect: no

History: Darwin (1868) wrote extensively on the number of tail feathers in pigeons. Morgan (1918) quotes relevant passages from the second (1875) edition of Darwin's book.

Inheritance: T.H. Morgan (the genetics pioneer and Nobel Prize winner for his work in Drosophila) published an extensive study of the inheritance of more than the usual number of 12 tail feathers in pigeons in 1918, and was compelled to invoke 3 or 4 loci to explain his segregation results. Like Morgan, Johansson (1927) could not illustrate single-locus inheritance.
