Does the split gene carry generation to generation? For instance if I breed a pure blue normal to a pure green normal all the green babies will be split to blue. If none of these green/blue offspring and there offspring never produce a blue bird, is the split gene still being carried or is it lost after the first generation or is it carried on forever until eventually a blue baby is born? before anyone answers I do understand about sex linked, etc. I just simply want to know if the split carries generation to generation.
