OMIA:001730-9031 : Stringy in Gallus gallus (chicken)

Categories: Integument (skin) phene

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: no

Species-specific description: "The primary and secondary wing and tail feathers of " stringy " birds are generally shorter than those of normal birds, the barbs do not spread out to form a normal web, and barbules are usually absent. The body feathers exhibit a ragged appearance. The toe nails and the premaxilla of the beak (bill) are unusually long. The upper and lower beaks are frequently crossed. Chicks homozygous for the abnormal feather condition have " sticky " (not fluffy) down, which is neatly parted on the. mid-dorsal line. "" Stringy " adult [male] birds are less vigourous than normal [male][male] and the volume of semen they produce is small (usually less than 0. 2 cm. 3). The egg production of " stringy " [female][female] is equal to that of normal birds of the same stock." (Buss et al., 1950)

Inheritance: Buss et al. (1950) reported autosomal recessive inheritance.
