In a case of mammalian coat color, the principal gene identified is C which codes for a tyrosinase enzyme. In rabbits four different phenotypes are observed in the order Full Color > Chinchilla > Himalayan > Albino (in order of the expression of gene ‘C’ and its
alleles). In a progeny obtained after crossing two rabbits, the percentages of Chinchilla, Himalayan and Albino rabbits were $$50\%$$, $$25\%$$ and $$25\%$$ respectively. What must have been the genotypes of the parent rabbits?
