Are certain comb types more dominant?

[aurajean515]

Not sure if this post fits in this forum but here goes:

I’ve been raising and breeding chickens for a while now but I’ve only ever had chickens with single type combs. This year, I’ve expanded my horizons and got some hens as well as a rooster, some with rose combs and some with pea. Of course I’m still breeding them and was curious as to whether certain combs are more dominant than others. If I breed a single combed rooster with a rose combed hen, what are the chances the chicks have either of those combs???

Thanks everyone

I moved your thread for 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)

Thank you! So if I breed a rose combed rooster with any single combed hen, all chicks will have rose combs with no chance of a single comb?

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.

Agreed.
Typically homozygous rose combs are better formed than heterozygous rose combs

Yes, a heterozygous rose combs are usually sloppier looking. I'll have to see if I have any good pictures of my Dominique cross combs.
