Genotype of Norwegian Jaerhone

[Steinagarden]

I found 1 thread about this before, but not enough replies or info. Does anyone here know the genetic code of the breed or could have a guess? It seems they must have different or mixed E-alleles, based on the chick down. They are not wild type, but E, eWh or eb and/or mixes of these.

What else? They come in light and dark "yellow/brown", but I can't find more information about that. Are they cream ig/ig (maybe not, only the rooster is light, what gene makes him light)?

Has anyone tried crossing them with a different breed and has photos of the outcome? (could tell me something about the genetics based on the other breeds known genetics)

I also know they are barred and autosexing (BB rooster and B hen)

Photos of the breed:

Males on top, females bottom

@rural mouse Would you know anything about this?

This is just what I think based on the photo...
The pictured ones look like barred red partridge to me (e^b/e^bB/BMh/Mh)
Some alleles of barring have a lot of white on the males. I can see the male is clearly gold-based, he still has the red on his neck, it's just he's got a lot of white due to the double copy of barring.

It's also possibly not an allele but a gene that modifies barring, I don't know. I do know some cuckoo d'Anvers males come out almost white sometimes.

The Males are: e^b/e^b, s+/s+, B/B, ig/ig.
Lemon Crele, but on Partridge Base.

Females are: e^b/e^b, s+/-, B/-, ig/ig.
Lemon Crele, but on Partridge Base.

Cream Legbars are lemon crele on a duckwing base and I think these look much darker than that?

These could possibly have Ml, or possibly Charcoal in addition.

New breed to me. Hmmm. Reading time.

I'm talking about the pheomelanin not the eumelanin.
I'm sure some Jaerhons have lemon but not the ones pictured.

The cream legbar hen I had looked really similar in color, a darker gold, so Mahogany may have been present, which does result in a darker color rather then a light lemon.
I only have a picture when she was a young pullet though.
