The combination of pigments expressed by melanophores black pigmentsAnerythristic definition yellow pigmentserythrophores red pigmentsand leucophores white pigmentsgives snakes their coloration.

Erythrophores synthesize enzymes that convert carotenoids into the red pigment erythrin. The anerythristic mutation is the result of non-functional enzymes, thus erythrin is absent or decreased. There are two variations of this mutation that will result in an anerythristic boa. The first is referred to as a type one mutation which originates from Colombian boas.

The second is referred to as a type two mutation which originates from Nicaraguan boas. Xanthophores synthesize enzymes that Anerythristic definition carotenoids into the yellow pigment xanthin.

The axanthic mutation is the result of non-functional enzymes, thus xanthin is absent or decreased. Both anerythristic and axanthic mutations are recessively inherited. Anerythristic definition In order Anerythristic definition express these mutation a boa must have two homologous alleles of the anerythristic mutation gene.

If a boa only has one mutated allele and one normal allele then the animal is heterozygous and the phenotype will be that Asa akira fleshlight a wild boa.

However, the allele for the anerythristic mutation can still be inherited by offspring.
