Sex- linked Information

[tadkerson]

after taking a closer look at the Columbian Rock birds I do agree most of them are wheaten based, while most columbian wyandottes are brown(eb) based..

Tim the extra eumelanin on their saddle(on columbian wyandottes) is due to eb right?

here is a light sussex(wheaten columbian) rooster with no visible saddle eumelanin(on the right) and a columbian Wyandotte with visible saddle eumelanin

Marvin,

I have not read any research manuscripts or conducted any breeding experiments that would indicate that the brown allele and the wheaten allele act differently , with respect to black in the saddle hackles, when columbian restricted. I am not saying it does not but I can not answer with a yes.

I haven´t either. BUT seeing how wildtype wheaten(all other genes wiltype except the e allele) look very devoided of eumelanin compared to wildtype eb brown(at least on the females as the males look very similar) I suspected this has something to do with the lack or pressence of saddle color. so I´m just guessing.

It means the Barred rock hen is not a pure Barred Rock. She is split Extended Black and something else. I'm not going to try to guess what that something else is.

A Barred rock is generally Silver, which is a sex linked gene. SInce the chick is red, there is an excellent chance it is a pullet.

I was thinking the hen would not be pure, and how knows what she could be!
I hope it is a pullet!

Ridge Runner is correct.The barred rock is most likely carrying birchen and the extended black gene. I have produced chicks that were birchen/wheaten that had a down pattern similar to the chicks in the illustration. It could also be wheaten and any other E locus allele also. Most probable is birchen. Wheaten in the chicks would come from the RIR rooster.

The second part of your question. Easter eggers (ameraucanas are not red) have pea combs not rose combs. If the BO crossed with a barred rock hen, then the chicks should be black with buff faces.

Tim

He does have a small comp with multiple rows, he is mostly the same color as a RIR, of course he has colors all over, one of his brothers was almost all white with red splash. He may not be full blood either, with his color I suspect he has a RIR (or similar) in his background. As for the BO I can only ID 2 chicks as his, both look just like him, and only him. This is a surprise as he was quite a busy guy!

HELP! HAS ANYONE EVER crossed a silver laced wyandotte hen with a rhode island red roo?? Have pics of the cross?? please help!

I have a few, from a random cross. I on ly know the pullet parents because of the lacing from the mom and the red from dad. I have a few that are red laced. Rather pretty. Males from this cross are not identifiable. Sorry.

the Pattern gene(lacing) is an autosomal gene, so both gender obtain a copy of Pg. they would be Pg/pg+. males will be golden culumbian

question for the experts.
ok,apa sop says light sussex male hackle is black laced with white. english sop says white feather striped with black. there is no Pg in light sussex.
so is this a color balancing difference?

other genes my be affecting the hackle, but its not Pg

========================
ok, so if one has the apa sop hackle and wants the english sop hackle...does one focus on narrowing the black stripe...or widening the white edging. this is on a wheaten-based bird. how does one make the change show up in the female hackle?
thanks,
karen

i have been trying for a long time to find the proper thread with folk in the know to answer these questions.

Quote: DO you mean the boys look buffish with black in tail and neck??? I didn't get any of those. I did get a slew of black barred males with the barring limitded to the neck and tail though-- that's the restriction of columbian , right?
