I dont understand...

Heterozygous = one copy of the gene is present. Examples--het albino, het Russo BEL, Lesser Platinum, Cinnamon.

Homozygous = two copies of the gene are present. Examples--Albino, Piebald, Blue-eyed leucistic, Super Pastel.

Recessive: The gene only changes the animal's appearance if two copies of it are present. (Albino, Piebald)

Co-dominant (or incomplete dominant): The gene changes the animals appearance if one copy is present, but changes it in a different way if two copies are present. (Pastel/Super Pastel, Lesser Platinum/Blue-Eyed Leucistic)

Dominant: The gene changes the animal's appearance if one copy of it is present, and changes it in exactly the same way if two copies are present. (Pinstripe).

Unproven Dominant: New term coined for 'we don't know what's going on, because one copy of the gene changes the animal's appearance, and no animals with two copies appear to exist at all, or they haven't been discovered yet). (Spider)

Of course, things actually do get more complicated than that.

Alleles and complexes: Some genes occur on the same locus. To make this understandable, let's just pretend this means they are DIFFERENT mutations of the SAME gene. Because they are the same gene, each animal can still have only 2 copies of that gene, one from each parent. As a result, if the animal inherits 2 mutant genes--but they're on the same locus (they're different mutations of the same gene), then it will show a modified super form. Examples of complexes: Lesser Platinum, Mojave, Russo, Mystic, etc--all are on the same locus, which is why breeding a mojave to a lesser can produce a BEL, and why breeding a mojave to a mystic can produce a mystic potion.

Another complex is the albino complex--interesting, because albino is recessive. Albino, Toffee, and Candy are all on the same locus, so breeding an albino to a Toffee can produce Toffinos (which look like toffees).
