My understanding is that albinism in other animals is actually coded
for by more than one gene, each gene coding for a biochemical step in
the synthesis of melanin. However, most angelfish breeders treat albinism
as a single gene. This may be appropriate from a practical breeder's
perspective if the multiple genes for albinism exist and do not operate
independently (i.e. they are linked).
