Thanks to all the posted suggestions in review #1 thread. I think I've gotten most of the suggestions in. Sorry for whatever I may have missed. Please review again and let me know what I may be missing.
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/Amelanistic (Tyrosinase negative): Recessive - a lack of melanin (black pigmentation) Kahl and Sharp strains.
Anerythristic - Recessive - a lack ______ (red pigmentation) two known strains (type I and type II)
Hypomelanistic - Hypo - Dominant - a reduction in the black pigmentation
Caramel Albino (Tyrosinase positive) : Recessive - Colombian and Nicaraguan strains
Caramel Hypo (Boawoman Hypo)-recessive-a Hypomelanistic trait with similarities to Colombian T-plus Albinos and Pastels.
Pastel - Polygenic - A line of boas selectively bred for less than normal black pigment, not related to a single gene pair.
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 Caramel Hypo (Boawoman hypo)- ??????
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? 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 ----- Thanks,
