Buckeye X Cornish X breeding project. Third generation pics pg. 20

They look really good Jeff . I'm pretty sure the pea comb is an incomplete dominate ; they can sometimes get big , sloppy , or be a walnut comb if they're not pure for pea .
 
really great! wow! your hens are shaped a lot like mine, but the rooster is totally different so interesting to see. My hens are literally eating double the ration of all my other birds, but the huge roos are actually quite thrifty . . . are you noticing the same?
 
Interesting on the pea combs, I did notice that most of the hens had the small tight pea combs... however that may change in the next generation.

Yes, the rooster is extremely agile for how big he is. Very powerful too, so it's not just a big sloppy mess like the cornish roosters. But I'm wondering if we will degrade as time goes on like some of the broiler breeder roosters? Not really sure, but do know they have a huge appetite and are very dense.
 
"Genetics of the Fowl" confirms what SteveH said. Incomplete dominant.

They also add that in pea comb birds "a ridge of thickened skin runs lengthwise of the body in a mid-ventral line just under the keel of the breastbone." I think that's interesting. You might watch for that when you butcher.

Interesting on the keel bone.... does the book have a better description of what that is? Not too sure... I've notice the thicker skin on the keel bone on all the roosters, both pea and single comb birds had it. I thought it may have to do with age.

Also what exactly is incomplete dominant? Not great at genetics.
 
Also what exactly is incomplete dominant?

Best way I can explain it is that recessive takes two copies of the gene to be expressed at all ; one copy can be in the bird's genetics but you can't see the charteristic at all in the bird's appearence . Dominate will show in the bird's appearence and mask a recessive with only one copy . Incomplete dominate is partially expressed with one copy , but more completely masks a recessive gene with two copies . And if you're not confused by that , some genes are sex-linked and female chickens can only get one copy while the males can be pure for them

ETA : Both my WLRC pea combed cockerals and my CX cockerals [ although single combed ] have a thick ridge of featherless skin over the keel bone , not sure about the pullets

It just means that when there is one dominant and one recessive gene, the trait is somewhere in between the two (but generally tending toward the dominant).

Totally made up example: suppose there was a dominant gene for blue coloring and the matching recessive was yellow; and that the blue gene is incompletely dominant.

If there are two dominant blue, the chicken is blue; if there are two recessive yellow, the chicken is yellow. If there is one dominant blue and one recessive yellow, the chicken would be greenish blue.

Overly simplified I'm sure, but that's the gist.

I think that's a pretty good example , but if I understand it correctly : dominate blue X recessive yellow = blue ........... incomplete dominate blue X recessive yellow = green

ETA : The " Blue " gene in chickens is incomplete dominate and one copy dilutes black feathers to blue , but two copies dilute black feathers to mostly white with a little blue showing which is called splash

Yes, I meant the example to be for incompletely dominant, but should have been more clear.
 
First eggs from the crosses are in.... will be setting some in a couple of weeks when the eggs get up to size. Right now they are small pullet eggs.
