Help! Can anyone point me to information on Salmon morphs that is easy to understand? Most of what I've found is over my head.:0
Thanks

There has been a few posts this past week concerning genetics I would suggest reading. Additionally you should check out salmonboa.com.

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
Super Moonglow – homozygous anerythristic / homozygous albino / homozygous hypomelanistic
Pewter - homozygous type II anerythristic / homozygous blood

Locale Related Color Mutations:

Sunset – homozygous hypomelanistic having 50% Hog Island Boa blood
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

I could not open the stuff you sent me about this very subject. Glad to see it here.
