Need a little help, this little one is 11 weeks. Roo or pullet?

Dominique's don't have a Buttercup comb.

That's not a buttercup comb. Just a goofy rose comb. Even has the spike.

It's split down the middle, & Buttercup occasionally is fused at the back.

I understand what you're saying but it's still a rose comb The split is pretty normal to some extent. My RC RIRs all had it, it was less pronounced in the hens but here's some pictures of the rooster. This chick will grow up and look similar. These birds will look a bit different than the neat rose combs such as the ones found in Rosecomb bantams

There must be some Duplex gene influence creating the split, if that makes sense.

The Dominique and this circled one are definitely cockerels. Individual pictures of the other lavender birds are needed View attachment 2703299

Agree.

Here's an article https://www.diva-portal.org/smash/get/diva2:845131/FULLTEXT01.pdf Sounds to me like there's just a lot of phenotypic plasticity and they haven't isolated the modifiers yet. There's just a lot of variety in rose combs. It doesn't sound to me like the duplex gene is causing this but it sounds like there's a lot of research needed

Bottom two look to be cockerels!

Oh boy! We were hoping for more pullets. How many Roos can be ok with each other ? Ideally looking for 3-6 hens and 1-2 Roos. At what age do the start crowing?
