Are certain comb types more dominant?

[Redhead Rae]

Here is an ok picture. These are Black Cochin/(Dominique/RIR) cockerels. The bird on the left wasn't as developed as the bird on the right. You can see how sloppy the points are on the right hand bird. He also doesn't have a defined point on the back of his comb.

This is what a proper rose looks like.

This is what a proper rose looks like.

But I thought there were different types of rose combs as well... My Wyandotte's comb is the same shape, but very flat without bumps or ridges, compared to my hamburgs' rose combs, which are bumpy.

If the rooster has two copies of the rose comb gene, yes, all your chicks will have rose combs. If he is split for single/rose. You'll get a 50/50 mix if bred to a single comb hen.

Very interesting. Thank you

Single comb is recessive
Rose comb is dominant
Pea comb is dominant
Walnut com is RosexPea and is dominant
Buttercup is dominant
V/horn is dominant
Strawberry is dominant

Single x Rose = 100% rose
Single x Pea = 100% pea
Rose x Pea = 100% walnut (Silkie comb)

What's the relation of all of the dominant ones to eachother? Do they all just make co-dominances when crossed, or are some "more dominant" than others?

I'm not well versed enough on comb genetics to answer this with confidence.
I would assume they would become co dominant when crossed as when a dominant homozygous comb is crossed with a different dominant homozygous comb the offspring inherit one copy of each and therefore it should have a co dominant effect when bred to something else.

I'm not sure sure about any dominant crosses other than Pea+Rose = Walnut. The other comb types are fairly rare and not commonly crossed.

Buttercup crossed anything creates a smaller more muddled double comb of whatever it crossed with. In certain cases.
Horn/V comb x Buttercup comb

Walnut comb crossed buttercup comb

not trying to hijack thread here, but i have a blue silkie with a single comb.......otherwise looks pure silkie! no idea how that happens? been meaning to get a pic and post

Did you get the silkie from a breeder or a hatchery? Hatcheries are known for not being careful about keeping their stock homozygous for comb type and as such they will often get single comb chicks.

If you got the bird from a “breeder” they are probably a backyard breeder working with hatchery stock and not a show breeder.
