I've had a good look at the pics too, and I think the dark Tort is a Black... which would make sense as two look Dove. If it was an Umbrous Golden Tort there would be more in the way of cheek flashes and the belly would be lighter.
What mystifies me, Babyboos, is where has the Yellow gene come from? It has to be present in either parent. Shadow's pics aren't great but she doesn't look anything like she might be Tort. So that leaves Si... He must have Yellow.... but if he has then
all the females will be Tort.
The other possibility is that Shadow is a "hidden" Tort. These happen all the time in Tort hamsters & cats, and I have had personal experience of it. Sometimes the Tort pattern is so minimal that just a few overlooked yellow/cream hairs exist, and they look normal (non-Tort), but of course they would breed as a Tort.
If the sire is Yellow, and the dam is normal,
all the females will be Tort. But if the dam is Tort, and the sire normal, then the boys can be yellow-based OR normal, and the females can be either Tort OR normal. There's only 2 boys in this litter (and only 2 bubs in Si's previous litter) so random chance might have it that none are yellow-based. But if any of the girls are definitely NON-Tort, then Mum has to be a Tort, hidden or otherwise.
I'll refer you to a table of how Tort genetics works:
It seems to me that Si is the culprit - where Yellow is concerned... he is more likely to be a yellow-based colour than Shadow is to be a hidden tort! I wondered if he might be a Dark Grey + Yellow which would normally be Smoke Pearl, but with Umbrous on top. Or even a Silver Grey + Yellow + Umbrous.
It;'s one of those things... somewhere you have picked up the Yellow/Tort gene otherwise you could not
possibly have a Tort in the litter. And as it is dominant, ONE parent must have it. Question is... which one!!!
*rubs paws together* I love mysteries like this!
