OMIA 001742-9031 : Stubs in Gallus gallus

Category: Integument (skin) phene

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Considered a defect: yes

Species-specific symbol: Ht; sb-1; sb-2

History: A subset of this trait, namely stubs on hocks, was first reported by Serebrovsky (1926). Hays (1943) first reported on the more common type of stubs, namely "short partly grown feathers on the shanks and feet that appear in breeds that are normally clean-legged" (Somes, 1990)

Inheritance: Serebrovsky (1926) reported single-locus autosomal dominant inheritance of stubs on hocks; hence the symbol Ht. Hays (1943) postulated two autosomal loci, with recessive alleles now named sb-1 and sb-2 (Somes, 1990). The jury is still out.
