    Is one comb type dominate over another?

    For example single + pea = ??

    Or pea + rose = ??

    In the examples I had, the pea comb was dominant over a rose. I had some EE hens that crossed with a GL Wyandotte roo and all the chicks (6) had pea combs.

    Excellent question! I'll be curious to see responses.

    All of the EE or Ameraucana crosses to single combs I've had were pea-combed, or sort of "modified" pea combs.

    Because I'm working on two projects...one is a blue laced red cochin, the other, a blue laced red brahma. [​IMG]

    I also have the figure out the base colors for my brahmas...I only have a light but may get a buff to start that one, with...

    Pea and rose comb are separate genes. Single comb is the recessive allele to each.

    A bird who is RRPP will have a walnut comb, as will one who is RrPp.

    A bird who is rrpp will have a single comb. One who is RRpp or Rrpp will have a rose comb; one who is rrPp or rrPP will have a pea comb.

    There are additional comb genes that also interact and cause such things as a smooth or rough surface, spikes out the top of the comb, lack of comb, Y comb, buttercup comb.

    Yea, I can tell you why a Cat 416 Shuttle Shift loader has no transmission gear clash when shifting from foward to reverse under power, but this is WAY over my head.[​IMG]

    I bred a Buff Brahma rooster to a Golden Comet hen and there combs came out to be a tall, un-even rose comb...
