>Albino/Amelanistic - Recessive - a lack of melanin (black pigmentation) Kahl and Sharp strains.

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

>Anerythristic - Recessive - a lack of ______ (red pigmentation) two known strains (type I and type II)

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

>Hypomelanistic - Hypo - Dominant - a reduction in the black pigmentation

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

>Caramel Albino (Tyrosinase positive) : Recessive - Colombian and Nicaraguan strains

Caramel Albino (AKA Tyrosinase positive albino) - believed to be at least two independent mutant genes; all recessive - has less than the normal amount of black pigment. Colombian and Nicaraguan strains

>Caramel Hypo (Boawoman Hypo)-recessive-a Hypomelanistic trait with similarities to Colombian T-plus Albinos and Pastels.

Caramel Hypo (Boawoman Hypo) - recessive - has less than the normal amount of black pigment, similar 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.

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.

Sorry; I know zip about bloods.
