Thank you so much for the detailed reply!!Silver has a lethal factor, homozygotous. It has been reduce by breeding in foreign genes, but it is likely to accure again, if you are breeding too long silver with silver.
Grau Fee is Tibetan + Fee dilution.
I am figuring out at the moment, which dilution gene is in fact responsible for Fees.
The genes for Tuxedos are 4 different genes, all recessive.
White beard/bib, -breast, -primary wing feathers and -head.
How the final appearance is depends on which genes are active (double allele) and also individual intensity.
The bonus photos is probably Silver and Tibetan, both incomplete dominant, so they mix ... here is one of my Silver/Rosetta mixes:

I LOVE that silver rosetta! Might have another project on my hands now... Oh boy
