I see pictures of normal greys all the time and I've never seen one without the white circle around the yellow! Does that mean they're all split to whiteface?
I have my doubts about the accuracy of the alleged whiteface signs too. I have 13 birds, and the only ones that don't have signs of a whiteface split are the three that are visual whiteface. Of the remaining ten, I know for sure that 4 of them actually are split whiteface. I suppose it's possible that the other 6 are all split whiteface too, but I have special doubts about Ladybug. She has a visual whiteface mate but so far hasn't produced any whiteface babies.
All your male babies will be split lutino because they'll inherit the gene from their mother. Sex-linked genes do NOT pass from mother to daughter so none of your female babies will get the gene from her. But if dad happens to be split lutino you'll be able to get lutino babies of both sexes. He obviously hasn't given the lutino gene to anybody so far. If you want to know more about how sex-linked mutations work, check out the sticky at http://talkcockatiels.com/showthread.php?t=26845
Your male babies might or might not be split cinnamon on their other X, depending on whether or not they inherited the gene from dad. With each baby, there's a 50/50 chance that they'll get the cinnamon gene from dad. Any girls who get the gene from him will be visual cinnamon, and any boys who get it will be split cinnamon.
IF the father is actually split whiteface, there's a 50/50 chance with each chick that they'll inherit the whiteface gene from him. Your cinnamon girl has the "spot gene", a little oddity that I've been trying to figure out for about 5 years now. It seems to be strongly correlated with the whiteface gene so maybe a WF split really is floating around in this family. It also seems like it might be related to the pearl gene somehow, or at least it seems to disrupt the functioning of the pearl gene sometimes. If you search for "spot gene" on this forum you'll see a bazillion threads about it.
