    Ok just hatched some SG eggs but half of the chicks look like silkies. Please help me out a little and tell me if this is correct...

    Since I got both silkies and SG from the same set of eggs that would mean that they came from SG bred with silkie right?

    now if I keep the SG together will they make just SG or will I still get some silkies?

    All the SG have what looks like bow ties (but they are all still in bator so there might be one or 2 with out them) will I need a completely naked necked one to breed if I want some SG with out the bow tie or if I breed SG with bow tie to another SG with bow tie will I get the occasional naked necked SG?

    thanks [​IMG]

    You got 50% silkies because either both parents were heterozygous showgirls and you just got a high percentage of silkies or one parent was a silkie (in which case, all the babies will be heterozygous for the NN gene). If you breed heterozygous showgirls together, you will get approximately 25% homozygous showgilrs, 50% heterozygous showgirls, and 25% silkies.

    ok can you explain for a dummy lol I am gonna look up what heterozygous and homozygous means cause I have no idea!!!

    3 more are pipping though so if they hatch that will make 9 out of 12 shipped eggs pretty darn good to me!

    One white one has a naked back of the neck but what looks like a full beard in the front. I have named it Abraham. Cant wait to open the hatcher tonight/tomorrow morning and hold these little precious guys. I would take Chicks over jewlery any day!!! lol

    Quote:Homozygous means that it is carrying two copies of the gene and heterozygous means it's carrying one copy. If a homozygous bird is bred to a silkie (no NN gene), all the resulting offspirng will be heterozygous. If a hom and a het bird are crossed, f1 will be 50% hom and 50% het. Most het SGs will have a "bowtie" and most hom SGs will have a clean neck.

    Nice babies!

    Bow-tied birds are heterozygous (Na,na+); those with completely naked necks are homozygous (Na,Na). Silkies are homozygous for not-naked neck (na+,na+).


    (Na,Na) + (na+,na+) = 100% (Na,na+)
    naked + silkie = bow-tie

    (Na,Na) + (Na,na+) = 50% (Na,Na) & 50% (Na,na+)
    naked + bow-tie = naked & bowtie

    (Na,Na) + (Na,Na) = 100% (Na,Na)
    naked + naked = naked

    - - -

    (Na,na+) + (na+,na+) = 50% (Na,na+), 50% (na+,na+)
    bow-tie + silkie = bow-tie & silkie

    (Na,na+) + (Na,na+) = 25% (Na,Na), 50% (Na,na+), 25% (na+,na+)
    bow-tie + bow-tie = naked, bow-tie & silkie

    - - -

    (na+,na+) + (na+,na+) = 100% (na+,na+)
    silkie + silkie = silkie
