Hypomelanistic (Salmon) boas are the result of a DOMINANT mutation.
The Homozygous (Super) and Heterozygous (non-Super) forms look identical. If there was a phenotypical difference between the Homozygous and Heterozygous forms it would be CO-dominant.
Salmon (non-Super, the Heterozygous version) bred to a normal will yield:
50% Hypomelanistic (Heterozygous form)
50% Wild-type.
This will look like Half Salmon half normal.
If the Salmon is a Homozygous Salmon, also called SUPER.
When bred to a Wild-type you will get 100% Salmons (heterozygous form).
REMEMBER; Heterozygous means it carries ONE allele for the mutation, homozygous carries a matching pair (2).
An animal that has a dominant or co-dominant mutation will NOT LOOK NORMAL in the Heterozygous state.
DO NOT GO BY ADS. Often ads are posted saying an animal is possible dominant. This is WRONG. An Animal is either Homozygous or Heterozygous for a mutation. The mutation is either Co-dominant, dominant, recessive, or sex-linked recessive.
Jason, I saw you other post below, good information. I just wanted to make this one a little clearer for the original poster, I know you understand this stuff. If you could use capital letters at the start of sentences it would make your posts easier to read though
