Take it slowly........
Just start with one mutation like amelanism. It is a simple recessive trait.
Each parent gives one of it's 2 genes for that trait to the baby (they have 2 copies of every gene in their body). If each parent gives it an amel gene, the baby is amel. If only one parent gives it an amel gene and the other gives it a normal gene it is heterozygous or 'het' for amel. Simple recessive means it gives way to the normal gene. It's just a matter of chance as to which copy of the gene a parent will donate.
This applies to all simple recessive traits. Anery, Caramel, Motley, Lavender, Charcoal as well as amelanism.
When an animal is homozygous (has 2 genes the same) for amel AND anery (which are completely separate genes), you get a Snow. But just get the basic single, simple recessive gene down first.
