First Run of Cornish Cross Meat Birds and Super Excited!

The bird I'm talking about does not have a comb.

The geneticist still do NOT understand the difference ways that genes can interact. They still do not understand the ways that environment can influence gene expression. There is thing known as convergent evolution and also mutations. There are no absolutes.

No it is this simple. Single comb bred to single comb= 100% single comb.

If the slo gro broilers are single combed and there are any pea/walnut combed bird in the flock then it is the parent.

I freely admit I do not know the specific history of the parents. Any bird has the potential look like any other bird providing the correct genes are expressed. You can't say they don't possess the genes when you can't say how they interact in the first place, They still don't know what genes come into play to make a brown egg. If all chickens came from jungle fowl then all chickens have the tool kit in the right circumstances to become other than what the accepted norm is

Nothing is 100%

CLB= cream legbar?

If so, I have to say he would look normal for a CLB cross. Darker coloring overall- looks to possibly have a single dose of barring.. if he throws some non-barred daughters, this is proof(and this to me would be proof he is a cross/mix instead of pure CLB). He also looks to have a heavier build than typical CLB. His feathering also looks harder.

I have to call nonsense on pea comb being a "throwback" that just popped up. Pea comb is dominant, his comb is very typical of pea-single cross/mix. Pea comb also visibly reduces wattle size. There is just no way it can float down undetected for generations.

"Throwbacks" is something that happens with recessive genes like lavender, silky feathering etc. and not with dominant genes.

to be honest, the term "throwback" is all too often used to describe something not understood.

IF there are other breeds around, especially a pea combed bird the far simpler and far more likely answer is it's a pea combed cross.

You can call it nonsense if you want, but that bird is 100% Cream leg bar.

The parents had been locked in a breeding pen for months prior to this one being hatched. In talking to a genetics expert, he says that is what happens. Genetics is not always straight forward things hide and come out later.

He is not heavy at all the only reason he looks heavy is my hands under the fluff pushing his feathers out.

His parents took first place at the State Bird show two years ago, when we last had them, in the open division.

OK now we are getting somewhere with the bolded part. Why still the resistance though?

Yes we all know mutations, etc however for example if there is one pea combed bird in a flock of single combs and some chicks come up with pea combs, it is very reasonable to assume the pea combed bird is the parent. If someone insists on that one pea comb bird NOT being the parent is not reasonable.

Talk to other genetic experts. Not to that one.

 

[JRNash]

And the only absolute is that we do not have all the information we need. Ralph and I think along the same lines.
It doesn't necessarily even have to be a"throwback" it can be that this birds gene expression has combined in just the right way to mimic one of the ancestral birds.There is no way to know.
Scientists have already made chickens grow teeth and tails in experiments by turning genes that were there but dormant "ON"

 

[JRNash]

Your working under a premise of absolutes. Im working under one of "aint got a clue butthere it is"

 

[JRNash]

Maybe one of my nefarious neighbors threw em in my chicken pen.lol
