What is this comb and what will it look like?

[TinyRaptorDodos]

Prismo is a golden deathlayer(rooster) over white jersey giant(hen). She has always had a flat comb but I just recently noticed she has a single spike sticking out of it. Has anyone seen this before?

Rose comb they can have one or two spikes at the end here is my rose comb dominicker.

I'm pretty sure it won't look so much like a rose comb. But I am interested in what it will look like.

Her dad should give her what I’ve referred to as a “cushion comb” and I figured that totally canceled out the single comb from the mom but I guess not! I’ll try to remember to update this when she’s older

I don't have much experience with Deathlayers, but if they have cushion combs, then most likely what you're seeing is the rose comb portion of that coming out more because of the pea comb portion being heterozygous from the cross.

Cushion comb is a combination of both rose and pea comb genes, R/R P/P, plus some other gene or genes that smooth it out rather than it being wrinkly like a walnut comb. A single comb is the absence of either of those genes, instead having the wild type genes p+/p+ and r+/r+. The rose comb gene is fully dominant. Whether a bird has one or two rose comb genes, R/R or R/r+, they will express rose comb. Pea comb, however, is partially dominant. P/P individuals (without any rose comb genes in this case) have a smaller, tighter, neater pea comb compared to P/p+ individuals, who have a partial effect of the gene and that tends to be something in between a pea comb and a single comb, appearance-wise.

When you breed cushion R/R P/P to single r+/r+ p+/p+, you get all offspring that are R/r+ P/p+. Because R/R and R/r+ express the same way, the rose comb trait is simply expressed. And because the rose comb gene is expressed, the partial effect of P/p+ instead makes the individual have a comb somewhat in between the appearance of a rose comb and a cushion comb.

After reading that, I had to go catch my chick who has a pea/rose combed momma and single combed dad and I can totally see that now!! Mav (the blue chick) has the same just not as noticeable!
