Lavender patterned Isabel duckwing barred - lavender brown cuckoo barred - project and genetic dis

Barred is not sex-linked, right? Either sex can get a copy of the barring gene, but only males can carry two?

Barred is sex linked.
Yes hens can only have one copy.
Yes roosters can have one or two copies.
A hen can only pass it to their male offspring.
Thats why it is sex linked and how they use barring for black sex links.
With this project people are using the fact that females only get one copy.
When using the wild type (duckwing) along with barring the single dose females appear different at hatch then the males with a double dose.
Same thing happens with single dose females and double dose males on extended black. Such as sexing barred rocks by their head spot.
Barring can be used a few different ways as a type of sex linking. IMO it is probably the best sex linked gene.

So the chicks I hatched are showing sexable traits that I just can't see at the moment? If the female parent is not barred and the male parent is, then the barring is or is not sexlinked?

A bit crude -- but here's a Punnett square


The column showing only 1 barring gene would be the female chicks and the column showing two barring genes would be the male chicks. Both female and male chicks could be barred or unbarred from that pairing -- and barred male can only have 1 barring gene.

If this needs correcting -- someone give me a whap -- and I'll re do it.....

Here's the beauty shot of the baby-of-the-day


In the case of these chicks -- and these are the first from Twin II - there is much more variation in the down colors. It looks like the ultra light down would be males and the sharper chipmunk stripe would be females -- but at this point that is conjecture.


Male surrounded by two females?

Three females?

Very faded markings -- barely there dorsal stripes....
Will try to get more picts and update over the weekend or early next week.
ETA - 9 Isabel and 8 split. 3 of those splits were from "Jack" 3/3 of that Brinsea mini -- and all 3 were split. Of the 14 from "Twin II", 5 were splits. Ahh the chicken math.
Storm moving in - so I will probably loose signal -- back later.

Those chicks look really promising ChicKat.

Thanks so much! I can't wait until that happy day when I have clear and definite autosexing like the little chicks in that pair you posted earlier in the thread.

Teal is so cute with that little crest!! Green, do you know the parentage? Sheesh, they are all so cute!

Orange and Green are both from you, Robinson x Isabella. The other three splits were from eggs laid here, so either Jim or whoever she was with before.
