Morph: Amelanistic
Other marketing names:
Amel, Red Albino, Albino
Genotype: aa·aa
Eyes: Light Red, Orange, or Pink with Pink pupils.
Ventrals: Normal checkerboard pattern remains, only the pattern is in varying shades of off-white and yellow.



History:
The first Amelanistic Cornsnake was a male, collected in Stanley County North Carolina in 1953. It was first bred in captivity in 1959 by Bernard Bechtel who bred it to three normal females producing 46 normal looking  babies. On August 31st 1961 this trait was proved to be genetic when the first Amelanistic Cornsnakes were produced. Three female F1's were mated to a sibling male with a total of 24 viable eggs being produced these eggs contained 17 normal looking hatchlings and 7 albino. Subsequent captive breedings by Groves in 1965 confirmed Betchels theory of Amelanism being a simple recessive gene.

Appearance:
Amelanism means a lacking of the pigment melanin, which is the black pigment. An Amelanistic snake has no black on it at all, including the pupils. This leaves a very bright snake of reds, oranges, yellows, and whites. The background can vary between white to yellow to orange and even red. The boarders around the saddles which normally would be black is now white, and the color in the saddles is usually very bright reds and oranges. Several selectivly bred variaties exist.

Notes: Amelanistic shares the same locus as Ultra they are allelic, meaning it is Co-Dominant with Amelanistic. No other gene known in Cornsnakes reacts this way with any other, with the exception of the Motley & Stripe which are also alleles but Motley is Dominant to Stripe.
All that is needed to create a Ultramel is a Ultra and an Amelanistic and Ultramels are produced in the first generation. There are three possible genes at the Amelanistic locus, Normal, Amelanistic and Ultra

Normal A+
Amel aa
Ultra au

There are only two positions to fill at each locus which gives us the following possibilities

Normal -+.-+
Normal het Amelanistic A+.aa
Normal het Ultra A+.au
Amelanistic aa.aa
Ultramel aa.au
Ultra au.au

If you breed an Ultramel to any other cultivar the offspring will be either het Ultra or Amelanistic they can't be both.
It is not possible to have a Corn het for Ultramel they can only be het Amelanistic OR Ultra. A Cornsnake that IS het for Ultra & Amelanistic is an Ultramel. Het actually means one copy of the gene and since Ultramels share this locus then technically speaking they are het Ultra & Amelanistic. They can't be homozygous for each trait as this would require two copies of each gene and there is only room for one of each.

Selectively Bred Amelanistic Cultivars: Reverse Okeetee, Candycane, Sunglow and Flourescent Orange.
Morph combinations: Snow, Butter, Opal, Blizzard,  Fire
