What do you get when you cross a pea comb with a buttercup comb?

I tried to search this, and found a lot of nice info on comb genetics, but nowhere did it discuss how these two comb genetics interact.

I did find that pea is dominant over straight, and buttercup is (I think) semi-dominant over straight, but it did not say where buttercup would fit in between pea and straight.

I hope I put this in the right forum. I'm hoping for a somewhat scientific answer, if anyone knows the genetics on this. It seems that buttercup is controlled by more than one locus?

Thank you.

You are right. I do not know. I could not find much info about this, either.

I have wondered about this too, pea or rose with duplex. Cannot recall seeing any information on this either...

Sure hope someone who knows comes along and sees this.

Well, I was able to find this. It doesn't answer the question, but it sheds a little light on the buttercup comb genetics.

Nice find, thanks for posting the link.

I do have birds that either have D or Dc- they're mixed breed with Houdan being part of the mix.. had assumed it was D however have a rooster that has a perfect double comb... and hens with what looks like poor imitation of buttercup- single in front and a buttercup form in the rear part... so what is it?

Well, it did say that both the v comb and buttercup comb were incomplete dominant over singe comb, so it kind of sounds like your hens have the dominant part only affecting the back.

Just remembered the comb on her- any ideas what the genotype could be?
