A frizzle refers to a plumage pattern in domesticated chickens (Gallus gallus domesticus) characterized by feathers that curl outwards, rather than lying flat as in most chickens. The frizzle type is not a separate breed, but a variety within breeds.
Sex-linked barring is a plumage pattern on individual feathers in chickens, which is characterized by alternating pigmented and apigmented bars. [1] The pigmented bar can either contain red pigment ( phaeomelanin ) or black pigment ( eumelanin ) whereas the apigmented bar is always white.

The gene for the curling of the feathers is incompletely dominant over normal plumage; not all members of the breed have frizzled feathers. Frizzled birds are heterozygous for the gene; when two are bred, the offspring inherit the gene in the usual Mendelian 1:2:1 ratio: 50% are heterozygous and frizzled like the parents, 25% have normal feathering, and 25% are "over-frizzled", with brittle ...
