Cuckoo vs Barred?

[LilJoe]

Been wondering what the difference between these two varieties genotypically and phenotypically.
Help woukd be greatly appreciated.

Barring is melanin inhibitors that prevent any coloration, meaning it looks white, in a regular pattern that presents in bars or zebra lines.

Cuckoo does not have clear zebra lines so the inhibitor is more diffused creating a messier look rather than crisp bars.

You can have have two barring or cuckoo genes or just one.

Two genes means wider white patterns. In pure breeds, males will have the double bars/cuckoo while females the single bars/cuckoo as the barring gene is on the Z chromosome which also determines the sex (ZZ male, ZW female).

I am not sure what the genetic difference between the cuckooing and barring other than some sort of location coding that creates a straight line and one that is more diffuse???

I will be interested if someone can tighten up that fact (and clean up any of mine).

My understanding.

I think I found the answer in the difference between barring and cuckooing...it is the difference in feather growth genetics.

Barring produces melanin inhibitor (white) for both barred and cuckoo. When coupled with faster feather growth genetics, it produces the crisper lines while slower produces the messier cuckooing.

Thank you so very much. This was great help

They're the same gene.
Its barred on slow feathering birds and cuckoo on fast feathering birds.
Cuckoo isn't as crisp because of the faster growth. Barring is cleaner because of the slower growth.

Genotypically the same gene, the barring gene, which is sexlinked. Sexlinked basically means the hen can only get one gene, which it gets from her father, and the cock can get two, so he gets one from his mother and his father.
That's why the chicks from a black father and a barred/cuckoo mother are sexlinked. Black pullets from the daddy and barred/cuckoo cockerels having one barring gene from the mother and one nonbarring from the father.
However, it is barring if it it is the slow feathering gene. (Which is why exhibition Rocks grow feathers so slowly, the slower the feather, the better the feather.)

Cuckoo is fast feathering, for example hatchery barred Rocks should technically be called Hatchery Cuckoo Birds (because they have the fast feathering gene and don't look much like Rocks either.) https://www.bing.com/images/search?view=detailV2&ccid=QEKXHZg6&id=39D8F6087D688FD429DFBCA63C0A43AEB16E176B&thid=OIP.QEKXHZg6O1vdep770uk5LQAAAA&mediaurl=http://www.arcadia-farms.net/wp-content/uploads/2014/02/Barred-Rock.gif&exph=440&expw=440&q=barred+rock&simid=608027029357790334&selectedIndex=12&ajaxhist=0

You also have an interaction involving the slow feathering allele associated with barred phenotype.

What interaction is that?
