In giraffes, long necks (N), long legs (L), dark spots (D), and the ability to digest meat (M)are all dominant traits. What possible genotype could a long-necked, short-legged, light-spotted, meat-digesting giraffe have?
A)NnllddMM
B)NNLLDdMm
C)NNllddmm
D)nnLLddMM

The giraffe must have at least one dominant allele for each dominant trait it exhibits. Therefore, it must have at least one 'N' for long necks and one 'M' for meat digestion. Since it has short legs and light spots, it must have two recessive alleles for those traits ('ll' and 'dd'). Thus, the genotype NnllddMM fits these criteria.
