In mice, the gene (G) for colored fur is dominant over its allele (g) for white. The gene (N) for normal behavior is dominant over (n) for waltzing behavior. Pairs of nice were mated, and the following results were obtained: Colored normal mated with colored normal produced 38 colored normal, 15 colored waltzers, 11 white normal, and 4 white waltzers
What are the probably genotypes of the parents?
