Just a few quick comments because I haven't looked over your charts in detail (coffeee..... more morning coffee).
The first is that the only way to truly know that your foxie ears are solid is to bury them under an ear that is more DOMINANT and then pull them back out again with a sibling breed. And the same with the blonde whiskers. And illume if you want it.
Quote:once you breed siblings together so many times, the recessive gene (in this case ody boo boo ears) will show up 3 out of 4 times. Is this true?
I would say, in short, no. It looks like shorthand math. If you have buried a trait and are doing a sibling breed (where they both hide the same recessive from a parent) to get it back out there is a 1/4 chance that the dominant showing trait will become pure in the kitten (that both siblings will throw dominant). The descendants of this line will of course never throw that recessive trait again - it's gone. 2/4=1/2 of sibling breeds will have the dominant trait covering the recessive trait. These are the tricky ones, but with each kitten they are still going to have a 50/50 chance of throwing their hidden fur, which does not reach any kind of 3/4 mark for throwing recessives. And in 1/4 of sibling breeds, both cats throw the recessive and the recessive is then pure; the dominant is completely gone. I wonder if the 3/4 number you see is a kind of amalgamation of the last 3 options I mentioned here - the recessive Won't SHOW, but it will be PRESENT in either shown or hidden form in 3/4 of the cases of sibling breeds.
Kitty cat breeding is kind of a pain that way, trying to get all the traits solid. I certainly wouldn't bother to get everything pure, not all the time, but it sounds like you are picking and choosing your battles, so that's alright.
Edit post coffee: If you Really want to do this, you need to split Cathy and Nic up.
I don't know how much cattery space you want to devote to this but if you can have Cath and Nic working on the same project separately things will have a better chance of working out in the Long Run. But it's long, and you're going to bury the traits you want to pull them back out pure and that comes with no guarantees that you will get the cats to throw all their recessives when you want them too.
Catherine needs to go with a 9T cat that has a more dominant fur (though I wouldn't personally chide you for using another foxie blondie) that has a pretty eye, shade you want, a nice tail (swanky and fussy go well with foxie ears imo), an ear that is MORE Dominant than foxie, and blonde whiskers.
Nicholas needs to go with a 9T cat with foxie blondie or more dominant fur with pretty eye, shade you want, nice tail (preferably the same desired one that Cath is going with), a more dominant ear (which does NOT need to be the same as Cath's new mate and probably Shouldn't be the same) and whiskers that are More Dominant than blonde (so when the blonde shows up again you know it's pure*).
Best of luck. I wish you well. It's a good project.
*There are some caveats to this quick summary. Because of course the cats you buy to go with Cath and Nic have their Own Hiddens, and that can complicate the picture.
Karloff is dumb (and needs help with breeding)
