Question

A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:
• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.

Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.
