Brian Sharp imported a female albino wich birthed the first babies heterozygous for the Sharp strain.
All species of albinos are, and will allways be in high demand, as they are a key ingredient in many designer morphs such as snow and sunglow. The Sharp strain is relatively rare and sometimes more desirable because of their tendency to retain color and strongly contrasted tail markings. Personaly we do not work with this line because it look less clean than the Kahl line. Maybe the amelanistic trait is not controlled by a single mutant gene. A mere break down in the melanin-synthesis pathway can cause an irregular production of melanin. 
The two strains, Kahl and Sharp, are incompatible (non allele). If animals from each strains is bred together the offspring will be heterozygous for both, but there will be no offspring showing the mautation in the litter.
Also known as tyrosinase-negative or amelanistic.
The albino mutation is a simple recessive color mutation..
