Is this how Isbars breed true? I guess the only inconsistency is the shade, but they lay all green. Is that how he did it? Isolating the blue shell under a brown overcoat?
Yes, that makes sense now. So, is that correct? The last generation that I posted on the top would throw 25% brown coating with a blue under shell, making the eggs green in appearance?
Floof,
I’m planning on finding a breed that has a simple dominant brown gene, if I can’t find one, I guess there are both dominant and recessive genes on certain brown egg layers, I suppose this would be fine there would be no browns in the back cross to the Blue egg layer, and then if...
Thanks! Good to know. If I do achieve this goal, would the eggs be brown with a blue inside or will the blue inside show through and make the egg look green?
I might be completely wrong, so correct me if I am. I think there might be a way to produce Olive eggers that breed 100% true.
I’m going to assume this brown egg gene is monogenic (one gene determines the trait). Correct me if I’m wrong, but I think it would go like this:
First cross: Pure...
