100% correct.Nice to know, thanks!
As to the pea comb, it is just a simple dominant gene, like the blue egg gene. However, your EE is likely
to have two copies of the pea comb gene, which means everything that you hatch from her will have a pea comb.
If she has only one copy of the pea comb gene, which is possible since she is an EE, then all chicks have a 50% chance of having a pea comb.
A single comb means the chicken has nothing else hiding in there comb wise. Single comb is recessive, really just a blank spot. Two blank spots and you get a single comb.
A rose comb works exactly like a pea comb.
However, one pea comb gene plus one rose comb gene equals a walnut comb.
