The chances of infertility for a Rose Queen is practically unknown, because it can be created by a number of different combinations.
A Rose Queen is a hybrid between a midas, red devil or midevil and a Paraneetroplus (Paratheraps/Vieja) or a BP. Or a descendant of such.
So yes, indeed not a flowerhorn.
I think synspilum could also be in the mix.
