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?
