Correctamundo...the grey and dilute genes are totally separate genes and are not mutually exclusive, so you can have both. Off hand, I can't recall having come across a grey dilute, but the likely reason is who would want to cross a grey with a dilute to begin with, although I'm sure it has been done - I just haven't seen one...
