    Cats Critters Completely Indecisive

    I thought I had this figured out but some resent posts got me wondering. Here is how I thought it worked is it right?
    A BR Roo passes a barred gene to all babies,which is why even if I'm only hatching WL or EE eggs I get some barred babies (also have a EE roo) but a BR hen will only pass it on to male offspring.
    If I'm right please tell me if not correct me on how it works. [​IMG]

    you got it.....Barred rock Males are homozigous for the SEX LINk barring gen B on their two copies of the Z sex chromozome and the hens are Hemizigous for they only carry one copy of the Z sex chromozome Z/-
