Rose Comb Legbar Thread

[WHmarans]

Buckeye lays a brown egg.  Any one know if a barred Ameraucana has been developed yet?  Thoughts on what a pea x rosecomb would end up being?  I'm not at all fond of RIR, but think that the Buckeye might have  a better personality.  I hear that they are wonderful mousers.

X2 on the RIR. And Buckeye as mousers.

No Official Barred Ameraucana has been accepted yet, but there are breeders of Barred Ameracauna and Lavender cuckoo ameraucana breeding them, the problem accepting them to the SOP is that the Males Lack Dark Slate shanks, females do show some epidermal pigment but not dermal pigment due to the linkage of the Sexlinked Barring gene and the Id dermal inhibitor genes by like 1 or 2 centimorgans..


here is a nice Barred Ameraucana projcet pullet...

as for what Rosecomb and Peacomb cross would make? they would make what is called Walnut, but since the cross will be heterozygous for both genes then the walnut comb will be not as nice as with breeds with those combs

From what I've seen of walnut combs, they're pretty big goobery looking things. So, IMO, it'd be best to not mix the two types. But, pea and rose are dominant over straight. So without having any back ground in genetics, I'm guessing that if you used a straight comb with rose or pea, you'd have to then work on breeding the straight come out of the finished product. Yes???

Yes. No mater which type comb you use you will have to select for the comb you want out of the segregates.

One of the things I've noticed with some rose combed legbars I've produced is that sometimes they have a big, tall, thin base which to me shows signs of the single combs. That is why I was so happy to be far enough along with them that I can do a rose combed x rose combed cross this year. I think in the next couple weeks, I will let the rose combed male run with all of my legbar hens and put eggs at auction to get the bloodline out there into other hands, just in case something were to happen to my flock.

You are a wise man to spread the gene pool of your flock. I'd be interested in picking up some of your eggs next spring, as you are already doing what I was hoping to do.

you can have both Homozygous Rosecomb and homozygous single comb in one single bird, so I dont think you were seeing the effect of single comb per say, because single comb will always be there,

I don't understand this at all. Homozygous means two copies of the same gene doesn't it? So when an individual is Homozygous for a recessive gene, the recessive gene is expressed and the dominant gene is absent.. I thought. (I'll admit I only had the basics in genetics in school). If Heterozygous, (one dominant gene present and one recessive gene present) the dominant gene is expressed? I must misunderstand what Homozygous means in this context.

you are correct to assume Homozygous means two copies of such gene..... BUT... the Rose Comb gene which is R and the single Comb gene p+ are different genes located in two different chromesome so you can have a homozygous Rosecomb bird that is R/R and single comb bird that is also p+/p+ on the same bird, its like blue and lavender, both change the bird black feather pigments, yet they are different genes located on different chromosomes, while bl+/bl+ would mean a black feather pigmented bird, lav/lav will change that to a lavender color so you can have bl+/bl+ and lav/lav bird at the same time

My mind has been off the last week or so, the other day I started talking to a coworker in Russian without even realizing it until I saw how confused he looked.

I was thinking of heterozygous, the birds with the big floppy rose combs tend to throw more single combs.

If the weather would have been nice this week, I was planning on getting some pics of the flock but they're calling for rain all week.
