A number of genetic mutations have appeared in Corn Snakes, they are listed below as single trait corns.

Single Trait Corns

Lacking black pigment, melanin. Also known as Albino, Red Albino or Amel. Recessive.

Pic shows anery aztec

Anerythristic A
Lacking red pigment, erythrin. Also known as Black Albino or Anery.

Bloodred / Diffused
Diffuses, in particular, the lower lateral pattern, which increases as the snakes matures. Also removes the checker board pattern from the snakes belly. Also sometimes known as Blood. This recessive trait was originally named "bloodred" in the 80s by Bill & Kathy Love due to it's colouration. However in 2004, recognising that it is primarily a pattern morph, it was suggested that it be renamed "diffused". Many people continue to use the name "bloodred" to describe the diffused trait while others reserve the "bloodred" name for deep red, solid colour animals.

Dominant to normal. Reduces red pigment. Some believe this could be a hybrid.

Reduced red pigment and increased yellow pigment. Recessive.

Another recessive form of Anery but incompatible with Anery A. Often lacking the yellow colouring around the neck area. Also known as Anerythristic B.

Another recessive Anery but different to Anery A or B by replacing the black with a burgundy tinge. Also known as Ashy or Anery C.

Extreme fading of colour gives the snake an appearance of being permanently in shed. More extreme as the snake matures. The original anery versions of this morph are sometimes known as Blue or Blue Dilute. Recessive.

Hypomelanistic A
Reduced black pigment, melanin. Hypomelanism is a recessive mutation which also brightens existing colours, including the eyes. Also known as Hypo.

A recessive colour morph discovered in Germany. Also known as Chestnut, the amel version is referred to as mandarin (has no relation to mandarin rat snake). Some believe this could be a hybrid.

Lava or Hypo C
Independent form of Hypo. Recessive.

Similar to an Anerythristic but pale grey with a pink/purple tinge, often with ruby coloured eyes. Recessive. Originally known as Mocha.

Motleys have no belly pattern. Dorsal pattern varies greatly from blotches to stripes and anything and everything in between. Recessive.

An overall leucistic look with random scales of colour. It is unclear at this stage if this is a true corn. Recessive.

A deleterious neurological condition which affects the snakes ability to control its own movement. It was originally connected with, but now sadly not limited to, the sunkissed morph. Thanks to Cedar Creek Corns ( it has been proven to be recessive.

Stripes have no belly pattern and have two dorsal and two lateral stripes. Whilst the aim is for all four stripes to run the full length of the snake, most specimens have broken lines, particulary towards the tail.

Sunkissed or Hypo B
Independent and much brighter form of hypo. Recessive.

Note: The sunkissed gene has been connected with the deleterious recessive genetic mutation known as "stargazing" which is a neurological condition. We have therefore chosen to discontinue working with this morph until such time as we can reliably source 100% stargazer free sunkisseds.

Recessive pattern morph which looks like a stripe (almost positively not related to motley/stripe) but with granite like speckles further down the body. Also known as the original Granite.

New pattern morph displaying a "lined" pattern rather than striped and usually retains the darker borders. Dominant morph which some suggest may be a hybrid.

Ultra or Hypo D
Independent and much paler form of hypo. Believed to be a hybrid using a grey ratsnake, pantherophis obsoletus spiloides.

Pic shows Ultramel Motley Ultramel
Ultra and Amel alleles share the same locus therefore if a corn is het for Ultra AND Amel they are known as ultramels and have the appearance somewhere between the two. Looking almost like an amel with darker eyes. See note above on Ultra regarding hybrid possibility.

When combining any number of the above traits many different colour and pattern morphs can be produced.
Listed below are some of those morphs that we have worked with.

Also referred to as Coral Snow however not all Hypo Snows have the "coral" colour and not all Coral Snows have the Hypo gene.

Selectively Bred Corns

Dorsal pattern is misaligned and irregular. When both halves are completely misaligned and look like they have been split apart down the centre these are often referred to as zigzag or zipper corns.

As described above in single trait corns. A particularly deep red animal with very little pattern can be produced by selectively breeding the diffused trait.
Selectively bred stripe. The stripe is broken up and appears as "cubes".

Originally a locality "wild type" corn originating from Miami, Florida. Nowadays Miami has become a selectively bred trait identified by a grey or tan body with red or orange blotches outlined in black.

Miami Hypo
Miami + Hypomelanistic A

Miami Motley
Miami + Motley

Originally a locality "wild type" corn originating from South Carolina. Nowadays Okeetee has become a selectively bred trait identified by an orange bodied animal with red/orange blotches outlined with wide black borders.

Reverse Okeetee
Okeetee + Amelanistic. The amel version of the okeetee identified by wide white borders.

Ruby Freckled Snow
Genetically a snow corn but shows random patches of red pigment. Also known as paradox snow. The name paradox snow also refers to a snow which displays random patches of black pigment.
