Here are some details related to "Salmon"



Salmon (AKA Hypo) - Dominant - a reduction in the black pigmentation and often some increase in the yellow pigmentation.



Dominant = Trait is expressed when the gene pair is Het or Homo for the specific mutant gene. Het and Homo specimens are not 100% distinguishable from each other. Note, in some Dominant traits some of the specimens can be visually identified as Het or Homo.



Het = heterozygous = having two different genes within a gene pair. Most commonly one normal and one mutant but could be two different mutant genes.



Homo = Homozygous = having both genes within a gene pair the same. Can be normal or mutant.





All the above was cut and pasted from my genetics 101 doc below:





Terms:



Mutant gene = any gene that is different from the corresponding normal gene. Not necessarily a visual mutation.



Het = heterozygous = having two different genes within a gene pair. Most commonly one normal and one mutant but could be two different mutant genes.



Homo = Homozygous = having both genes within a gene pair the same. Can be normal or mutant.



Super = slang term commonly used for Homo dominant mutant gene pair.



Trait = Physical appearance that it distinguishable from normal.



Recessive = Trait is only expressed when the gene pair is Homo for the specific mutant gene.



Dominant = Trait is expressed when the gene pair is Het or Homo for the specific mutant gene. Het and Homo specimens are not 100% distinguishable from each other. Note, in some Dominant traits some of the specimens can be visually identified as Het or Homo.



Codominant = Similar to Dominant except the Homo specimen will have a 100% distinguishable appearance from a Het specimen.



Double Het = has two gene pairs where one gene in each pair is normal and the second gene is a mutant gene. Ie double Het for snow would have a normal gene paired with an albino gene and a normal gene paired with an anerythristic gene.



Triple Het = same as double Het except applies to three gene pairs.







Color mutations in boas:



Albino AKA Amelanistic) - Two independent mutant genes: both recessive - a lack of melanin (black pigmentation) Kahl and Sharp strains.



Anerythristic - Two independent mutant genes; both recessive - a lack of red pigmentation. Two known strains (type I and type II)



Salmon (AKA Hypo) - Dominant - a reduction in the black pigmentation and often some increase in the yellow pigmentation.



Caramel Albino (AKA Tyrosinase positive albino) - believed to be at least two indepenent nutant genes; both recessive - has less than the normal amount of black pigmentation. Colombian and Nicaraguan strains



Caramel Hypo (Boawoman Hypo) - recessive - has leas than the normal amount of black pigmentation, similar to Colombian T-plus Albinos and Pastels.



Pastel (AKA Hypo) - Polygenic - A line of boas selectively bred for less than normal black pigment, not caused by a single mutant gene.



Blood - Recessive - A Hypererythristic mutation.





Named Color mutation combinations:



Ghost – homozygous anerythristic / heterozygous hypomelanistic

Super Ghost - homozygous anerythristic / homozygous hypomelanistic

Snow – homozygous anerythristic / homozygous albino

Sunglow – homozygous albino / heterozygous hypomelanistic

Super Sunglow - homozygous albino / heterozygous hypomelanistic

Bloody Salmon – homozygous blood / heterozygous hypomelanistic

Moonglow – homozygous anerythristic / homozygous albino / heterozygous hypomelanistic

Salmontine – heterozygous hypomelanistic having 50% Argentine Boa blood





Pattern Mutations:

Arabesque – Dominant? - A genetic circle-back boa with a ladder-tail, Typically highly speckled and often having a very brown color with some specimins tinted pink.

Jungle – Codominant - Originally identified in Sweden,

Motley – Codominant

Stripe – Recessive

Reverse Stripe – Recessive?

Leopard – Recessive - dark color, a mix of underlying tones and marbled pattern.

European Squaretail - Recessive - long list of variable characteristics.

Scoria - Recessive? - Pink pattern-less with two parallel lines down back.

Aztec - Dominant?

Gray pattern-less - unknown
