First I will say this is very difficult for me to explain, and is also most likely not the case. It however may be impossible for a Blizzard to exist. At least with the Kahl strain albino.
An albino is an animal that is homozygous for amelanism. What does this mean, it means that on the chromosome pair that contains the allele for amelanism, both chromosomes within that pair have the same allele. In heterozygous animals, they have one for albino and one for wild (wild is dominant over albino).
Now, it is possible that Type II Anerys and Kahl strain albinos both have the allele for their respective traits in the same location. By inheriting one from each parent, this would mean they could be DH, Type II, or Albino. But they would not be able to show both the Type II and Albino traits in the same phenotype.
The genome of boas has not been mapped, and we do not know where each trait lies. For example sake, let's say that on the second chromosome pair on the tip of the right side is th allele for albinism. To be albino, both chromosomes in the pair would have to have the same allele in the right tip. Now if the gene for Type II Anerythristics is in the same location, and the animal had genes for both traits they can only have two different alleles in that location, so you have DH. This would make Blizzards impossible.
While all of this is possible it is very unlikely. However, if true, because Sharp and Kahl Albinos are not compatible (their alleles are in different locations) useing the Sharp Albino could produce a Blizzard.
However with this description made, I will say I fully believe Jeremy simply has been unlucky and not hit the 1/16 odds. I guess he's not one to take to Vegas!
Genetics are amaizing!

A possibility to the outcomes. - ChrisGilbert, Mon Apr 18 14:16:33 2005
