    When dealing with Het x Normal and Het x Het breeding pairs, all the Normal-looking offspring have a chance of being Het, but you can’t tell by looking whether or not it has the gene. In a Het x Normal pairing…each offspring has a statistical 50% chance of carrying the gene, so it is called “50% Het”. In a Het x Het pairing, all normal babies have a 66% chance of carrying the recessive gene and that’s where the “66% Het” term comes from.

    Great info. Thank you for posting it to help newbies like me.

    So I was hoping to find my answers here in this section but I didn't. So this is what Im curious about related to this subject:

    %50 x %50
    %50 x %66
    %50 x %100

    %66 x %66,
    %66 x %100

    Are they possible hets with just percentage that have to be mathematically figured out?

    And I would logically assume that a visual morph x with any % het would make %100 het, if not, visual morph.

    Please enlighten me. Thank you.

    All of the pairings that you mentioned apart from the 100% het involved breedings would have to be considered normal offspring.
    You can't breed 2 50% together and produce all normal looking babies and still consider them possible hets in regards to the clutch.
    You will need further breeding trials to establish if any of the parents are in fact heterozygous animals.
    50% simply means that one parent was het.
    66% means that both parents were het but the baby is normal in appearance.
    Since if you had 4 eggs, you have a 1 in 4 chance of producing a homozygous animal. Leaving you with 3 eggs, all normal appearing and a 2 out of 3 chance for the gene to have passed on. (66%)
    Do yourself a favour and get yourself a 100% het for the trait if you want to start proving out possible hets.
    Better yet, if all of the possible hets are for the same morph then buy the visual homozygous animal and have a 50% chance at producing visual morphs if the parent turns out to be a het.

    CO-DOMINANT:
    Butter – Blue Eyed Leucistic
    Cinny – Super Cinny

    What do the second names mean? like I know their morphs and all but is it just a different name or something? or what?

    Tyler this is more of an information thread. Specific questions you might have are likely going to get more responses if you start your own thread asking about what you need to know.

    That really helped a ton with knowing which morphs are recessive, dom and codom. Thanks a bunch!!!!
