Asherah is right the Toffee and Albino are compatible. In other words the two genes are allelic and share the same location on the chromosome or locus. That makes it possible to cross two different recessive genes and obtain a visual morph since it is equivalent to being homozygous at that locus due to the compatibility of the Toffee and Albino alleles.
Sounds a little complicated but apart from saying "they are compatible" I think it's the best I can do. Hope it helps ☺
