Thank you and yes, they look like that. I've bred my blacks for years with nothing else added. The white rooster must be carrying this B^Sd dilution.

What do you think these will mature to colorwise? White with spots?

Ahh! I had posted pictures on here of B^Sd chicks- homozygous cockerel and het pullet, also adult cockerel and pullet. Unfortunately they were hosted on photobucket and the laptop the originals were on had crashed....

The het cockerels and pullets don't look too far off from that chick. Essentially a much lighter than normal B pattern.

Edit- had not thought of Leghorns as a source. If those chicks prove to be B^Sd, it would seem to be it is far more widely used in the hobby than realized? My source was show bred white Naked Necks.

if B^Sd, it will feather out like a really light barred/cuckoo.

Homozygous roosters are white with 'grey spots and flecks'

It is excellent for cleaning up white and legs for sure.

So using these in a White flock is not a bad idea? And YES I've seen a LOT of Araucana's with that whitish/barred color as adults. Not fond of that color at All but if they make better whites, They can at least be useful.

What exactly is Imgur? Is it free? Limits on uploads?

Kaalnek, some of your photos from this post:





What I did to bring up Photobucket thumbnail size images (the only size available to link for free) is to put th_ (th with an underscore) in front of the image file name, eg changed the original filename barredboy8.jpg to th_barredboy8.jpg.
The full img code url (link):
Code:

Yes, imgur image web hosting site (https://imgur.com/) is free. You can upload as many images as you want (unlimited) except only allowed to upload 50 images per hour.
- FAQ - how to upload images
- FAQ -how to share images for Forums
* What you need is the BBCode for forums

I'll put further step by step instructions in the sticky "Posting Photos" thread.

Is there a leg color linked to this gene?

I need to take some time to find some of the pictures shared on BYC. There were a LOT of ghostly barred Araucana's posted. I've had some myself in the past.

So the gene for this has just been discovered? Any idea how it works?

Yes, Id locus (inhibitor of dermal pigment) is closely linked to B locus (barring, sex-linked dilution, sex-linked extreme dilution) 14%. But previous research by Punnett etc have noted B-id+ individuals (through test breeding), so they know that the B gene itself dilutes id+ dermal pigment too, as well as E or ER epidermal pigment.

The sex-linked spotty mutation dilutes id+ dermal, & E epidermal pigment very well, including beak colour, & dark eye colour is diluted to orange. I haven't confirmed as yet as to whether spotty is an allele of the B locus. No wild-type chicks have segregated from my het. spotty/barred rooster (to spotty or crele hens), only spotty so far. But I haven't segregated B/- or B/B without spotty from him either so far. Need to set more....
