Foxie - Dusty Slate is dominant to Toyger Tawny.
This proof comes from Ithildin Telperion/ Mondi Beaumont. Thank you very much. I know she's been working on this proof for at least a month.
FoxieDustySlate>ToygerTawny
Here we have two cats showing the Foxie - Dusty Slate. But Sally is hiding Toyger Tawny or more recessive, while Snubbie is hiding Toyger Snow. When the two are mated, a New Born showing Toyger Tawny is produced. The Toyger Tawny MUST have been Sally's hidden - that is the only place it could have come from - and it is pulled by Snubbie's Toyger Snow. Since the Tawny came out from under the Foxie - Dusty Slate, it must be recessive to it.
