What Anerythristic Type A looks like

Homozygous Anerythristic Type A. Removes all red, orange, and yellow pigment. Black/gray/white coloration with dark eyes. Silvery-gray background with dark brown-black saddle marks. One of the foundational corn snake mutations.

Removes all red, orange, and yellow pigment (erythrin pigments). Animals display black, gray, and white coloration with no warm tones. Background becomes silvery-gray; saddle marks remain dark brown to black. Eyes are dark/black (not red. Melanin is retained). Often called "Black Albino" informally, though this is a misnomer since melanin is fully present. Independent locus from Anerythristic Type B (Charcoal). Complementation confirms: Anery A x Charcoal produces wild-type-looking double het offspring, proving they are at different loci. Hatchlings from Anery A are often gray and white, becoming more silver/gray as they mature.

How to identify it: Gray-white base, dark gray/brown/black saddle marks, dark eyes. No orange or yellow anywhere. Clean silver coloration in adults. Can look similar to Charcoal but complementation distinguishes them.

How Anerythristic Type A is inherited

Anerythristic Type A follows a recessive inheritance pattern, carried on the Anerythristic Type A allele (locus AnerA).

What does het anerythristic type a mean?

Because Anerythristic Type A is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het anerythristic type a (heterozygous). A het animal looks normal but carries the gene, so pairing two het anerythristic type a animals produces, on average, one in four visual anerythristic type a offspring.

Combo morphs with Anerythristic Type A

  • Snow Motley

    Snow (Amelanistic + Anerythristic A) + Motley triple recessive combination.

  • Lava Ghost

    Lava + Anerythristic Type A combination. Highly reduced pigmentation producing a nearly white to faint lavender-gray animal.

  • Ghost

    Hypomelanistic + Anerythristic Type A combination. Produces a muted, ghostly gray-green to silver appearance.

  • Snow Stripe

    Snow (Amelanistic + Anerythristic A) + Stripe (homozygous Stripe allele at Mot locus). White body with a visible dorsal stripe in soft pink or lavender tones.

  • Sunkissed Snow

    Sunkissed + Anerythristic Type A combination. Functionally similar in appearance to Ghost (Hypo + Anery A) but at distinct loci.

  • Snow

    Amelanistic + Anerythristic Type A combination. One of the oldest and most recognized corn snake combo morphs.
