Araucana, ameraucana, ee ?
Okay you folks who understand genetics, help please. Is the double tuff a dominant or recessive gene? I had an clean faced, rumpless Araucana hen and an Ameraucana hen in with an double tuffed, rumpless Araucana Rooster. I have double tuffed chicks. I am wondering if I can tell for sure that they came from the Araucana hen and not the Ameraucana hen. Assuming the Ameraucana hen is a true breed she should not carry a gene for tuffs, correct ?

you need at least one copy of the gene to be tufted. so clean faced x clean faced will never give you tufted.
So one copy will give you tufted, which means it is a dominant gene.
no copies = not tufted
1 or more copies = tufted.
if your rooster was tufted ALL your kids should be tufted if he was carrying two copies. so, afraid that no, you cannot tell who is from your ameraucana hen because the roosters tufted genes will cover up her clean faced phenotype in the kids.
one way to tell is to keep the kids and then breed back kids to non-tufted, and then THOSE that hatch from their eggs should be a mix of tufted and not, depending on who mom was. but that's at least 22 weeks out from the date all your current chicks were hatched.

Thanks WLLady. I just might keep the chicks around and play with some breeding, it could be fun. I don't normally breed "mutts" on purpose, but some of the prettiest birds I have seen are backyard mixes :)
