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 whereas the apigmented bar is always white.
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.
There is only one plumage variety, sometimes called 'barred Columbian': it resembles the Columbian pattern, but the primaries, secondaries, hackles and tail feathers are barred rather than solid black. [8]: 57 The comb is single and five-pointed; it, the wattles and the earlobes are all bright red. The beak is a reddish horn color, the eyes a ...
Figure 1. Feathering types in ten-day-old chicks.Left: Fast normal-feathering chick. Right: Delayed-feathering chick carrying sex-linked K gene. Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
"Recessive white" chickens may be potentially black barred or of some other color pattern, but does not reveal this, unless they are submitted to a progeny test. White Plymouth Rock chickens carry a considerable mixture of genes taken from other breeds different from the original Barred Plymouth Rock from which the white variety originates.

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 ...
