Yes indeed, you would get siamese and burmese.
A siamese has the alleles ch/ch at the C-locus, the burmese has ch/cch.
Search the web about Punnett Squares to learn hoiw to predict the offspring.
Punnett Squares are diagrams that are used to predict the outcome of a particular cross or breeding experiment. It is used to determine the probability of an offspring having a particular genotype. The Punnett square is a summary of every possible combination of one maternal allele with one paternal allele for each gene being studied in the cross.
In this example, the mice have the genotype ch/ch and ch/cch. They can produce gametes that contain either the ch or cch alleles. The probability of an individual offspring having the genotype ch/ch (siamese) or ch/cch (burmese) is 50%.
Just start reading about genetics, it is simple.
