Color genetics questions with pictures

Could anyone give links to wheaten pics?

Buff orpintons are wheaten.​

Ok!

But what gene makes the pattern brown? I mean, wheatens do have black pigment, don't they? I don't see how it would explain brown lacing.

And I'd be very interested if they have some brown or dun gene. It would make possible to develope solid browns with extended black exc. I haven't seen those colors anywhere in Finland

Well, they have a wheaten base, but they aren't wheaten coloured

True,

Basic wheaten colour with nothing changing it is like these wheaten Marans.

Lots of colours, like Rhode Island reds or Light Sussex are also wheaten based. Have the same gene that makes the wheaten marans & then other genes which change the colour.

Buff - I looked at some buff pics and could these be just some sort of buffs? Chicken calculator at kippenjungle.nl says buffs are wheaten, red, dilute and dun! But the calculator gives the same image with only wheaten and dun. Well, it gives the same image with partrige and dun also, so I don't know

But the point was (I think), that according to the calculator, buff has a dun-gene? Is that so? I'd love to have dun-gene

That would be nice.

Henk says some buffs carry dun.....maybe you're hens have brown markings because of dun.

Unfortunately, no. Some buffs carry dun, but many don't. It might be dun that is replacing the black in your birds, however.

There are a number of "recipes" to build a buff bird. Yours are obviously carrying Pg which give the multiple lacing. A guess a good question is whether that can be built on a wheaten base versus an e^b base?

So how to test, if they have dun or not (or some similar black diluting gene)?

But isn't dun a heterozygous form of the dun-gene and in homotzygous form the colour is khaki? The breeder says they breed true, so maybe it's not dun afterall... What about choc?

I think I'll have to try to get a rooster of the same color to get more of these and maybe then do some test matings.

That is so.

I can't say why, but as I said earlier I have some brown tails & flights (& some markings) in my buff & red projects. I know mine have neither dun nor choc......wish they had.
I recently culled out the chicks with a lots of markings. I'll look in a smaller chick pens & see whether I have any showing up.​

Siimis,

Your birds are so called "braungebänderte".
They are pencilled plus some unknown factors that eliminate the black breast from the cockerels.
My speculation is Co/Co Pg/Pg.

The same factors, that eliminate black from full buff, added to a pencilled bird could have this effect also.

There are topics at the-coop about this mystery.
