Boa genetics is the same as all other genetics. It would be fairly lengthy to explain the punnent square (just google it, there are plenty of websites that will explain it well).
Basically you have two alleles for each trait. You get one allele from each of your parents.
For a recessive trait to be visualy different in appearance one must have recieved a mutated allele from each parent (ex. albinism).
For a dominant trait to be visualy different in appearance one must only reciveve a mutated allele from a single parent (ex. hypomelanism). One can recieve a mutated (dominant) allele from each parent, but will visualy have the same appearance as if they had only received one.

That is the basics ... here is a list of boa genetic mutations:
Color Mutations:
Albinistic – recessive – two strains: Khal and Sharp
Tyrosinase Positive Albinistic - recessive
Hypomelanistic – dominant
Anerythristic – recessive – two strains: type I and type II
Pastel – polygenic
Blood - recessive

Color Mutation Combinations:
Ghost – homozygous anerythristic heterozygous hypomelanistic
Super Ghost - homozygous anerythristic homozygous hypomelanistic
Snow – homozygous anerythristic homozygous albinistic
Sunglow – homozygous albinistic heterozygous hypomelanistic
Super Sunglow - homozygous albinistic heterozygous hypomelanistic
Bloody Salmon – homozygous blood heterozygous hypomelanistic

Locale Related Color Mutations:
Sunset – homozygous hypomelanistic having 50% Hog Island Boa blood
Slamontine – heterozygous hypomelanistic having 50% Argentine Boa blood

Pattern Mutations:
Arabesque – dominant?
Jungle – co-dominant
Motley – co-dominant
Stripe – recessive
Reverse Stripe – recessive?
Leopard - recessive?
