Unique Color- "Pied"?

[Sicilianu]

Hi everyone. Saw a few birds of a Russian bantam breed posted on Russian website and have never seen this color pattern before. I am not sure if this is a variant of a type of mottled, a modification of mottled with other genes, or something else altogether. I have never seen large white patches like this combined with large colored sections. Any thoughts about this or other birds you have seen with a similar pattern??

Interesting coloring - I wonder if they breed true.

I would at all be surprised if it was another mutation on the mottling locus, considering there are so many.
Actually, I’m almost certain it is, but is it a new one?
I’d be curious to see the website.

I wonder if they breed true as well and if it is on the mottling locus. Here is the website. This thread is about Russian breeds in general so you may have to go pages into it to find the one I posted. Russian website link

Scroll down on page 119 . You can see some of these birds from the same breed have normal mottling as well.

Also I found out is called the Altai bantam - Бентамка алтайская

Fixed for you.

There are many mottling allelic mutations that have been genetically sequenced and interestingly enough the sequenced on Millie Fleur found no mutation or that they carry the Mo+(non mottling) sequence, but they are obviously mottled so the mutation on the mottling allele is on a non-coding region. I also suspect that the white crested black polish also have a similar mutation.

Wait, are you saying that Mille Fleur is not Buff+Colombian +mottling? Oh dear.

Edited after reading through the above link:

Ok, so what I am taking on that is, the mottling we see in Mille Fleur is either a mutation in a “non-coding“ sequence of DNA, or it is found on some other locus. Is that what I should understand?

Thank you

That is a correct assessment. I would Say That is a non-coding mutation of the mottling allele.

So which one would you say it is on these birds?
