The coat color in mink is controlled by two codominant alleles at a single locus. Red coat color is produced by the genotype R1R1, silver coat by the genotype R1R2, and platinum color by R2R2. White spotting of the coat is a recessive trait found with the genotype ss. Solid coat color is found with the S- genotype.
Part B
What is the expected phenotype distribution for the cross ssR1R2 × SsR2R2?
Express your answer as four numbers separated by colons.
spotted platinum : spotted silver : solid platinum : solid silver =
Part CIf the cross ssR1R2 × SsR1R1 is made, what are the progeny phenotypes?
A. spotted platinum
B. spotted silver
C. spotted red
D. solid platinum
E. solid silver
F. solid red
