If ChrisGilbert's suggestion (that Sharp albino and Moore caramel are different versions of the same gene) pans out, we can predict the breeding results. In the following list of matings, I will use (name1)//(name2) for the genes involved. The "//" symbolizes a pair of homologous chromosomes, with gene (name1) located on one chromosome and gene (name2) located at the same position in the second chromosome. In other words, "(name1)//(name2)" is a single chromosome pair.
