Answer Key: 1. male wolf genotype: nnbb (must be homozygous recessive for both traits) so gametes are nb and nb 2. heterozygous female wolf: NnBb and gametes: NB, Nb, nB, nb 3. Genotypic ratio: ___25% normal color & brown eyes; 25% normal color & blue eyes; 25% black color & brown eyes; 25% black color & blue eyes...
