Correct, the non-tufted chickens should produce non-tufted offspring.So these non tufted birds produce non tufted offspring or the chicks might be tufted?
Sorry for the too many questions.
In Greece there are the tufted ones.
Genetics and breeding outcomes:
Tufted bird has 1 tuft gene and one not-tufted gene. It can give tufts or not-tufts to each chick.
Non-tufted bird has two genes for not-tufted, and that is what it gives to every chick.
Dead bird has 2 tuft genes (one from each parent.)
If you breed non-tufted birds together, chicks should all be non-tufted.
If you breed a tufted bird to a not-tufted bird, about 1/2 of chicks get tufts, 1/2 do not get tufts, no birds die.
If you breed a tufted bird to a tufted bird, about 1/2 of chicks get tufts (tufted gene from one parent, not-tufted gene from the other parent). About 1/4 of chicks get no tufts (not-tufted gene from each parent.) About 1/4 of chicks die (tufted gene from each parent makes 2 tufted genes, which is lethal.)
