A barred hen has only 1 copy of the barred gene that is y they are darker than the barred roosters... if bred to a none barred rooster all hens will not be barred and all roosters will have 1 copy of the gene and will be a darker color like there mom...
a barred rooster that has 2 copies of the barred gene is a lighter color... if bred to none barred hens all hens will have 1 copy of the barred gene and will be "pure" for barring as they can only have 1 copy... the roosters will be none barred... NO A rooster with 2 copies of the barring gens as they should have will pass the barring off to 100% of the chicks. If the hen from this cross is solid the roos from this cross will have only one copy. All the pullet will have 1 copy like they should
if u use a rooster that has one barring gene over a none barred hen u will get 50% barred hens and 50% none barred hens and none barred males...
See below for the correct %
if u breed a single barred rooster to a barred hen all the hens will be barred and 50% of the roosters will be single barred and 50% will be double barred...
See below for the correct %
so yes assuming your GC are based on BC if u use a BC hen under a GC rooster there daughters would be "pure" GC...
Quote: If you use a roo with 1 Copy of barring over a solid hen you get 25% barred pullets 25% Solid Pullets and 25% Barred Roos with one copy and 25% Solid Roos
If you use a single barred roo with a barred hen you get 25% barred pullets 25% solid pullets and 25% roos with one copy and 25% with 2 copies.
The HEN CAN NOT PASS any Barring to pullets..... all pullet barring comes from the ROO.
Barred roos will pass barring to ALL off spring pullet and roo. Single barred roos will only pass to 50% of each gender of chicks.
