Question

use the information to answer the following question.
nose color is an inherited trait in dogs. two puppies from the same set of parents have different colored noses. one puppy has a pink nose and one puppy has a black nose.
how can puppies from the same set of parents have different color noses?
a the pink - nosed puppy and the black - nosed puppy must not be related.
b the pink - nosed puppy has a different number of chromosomes than the black - nosed puppy.
c the pink - nosed puppy and the black - nosed puppy inherited different combinations of the genes for nose color from their parents.
d the pink - nosed puppy inherited all of its genes from its mother, and the black - nosed puppy inherited all of its genes from its father.

Explanation:

Inheritance of traits (like nose - color) in dogs is based on genes. Each puppy gets a combination of genes from both parents. Since the two puppies (pink - nosed and black - nosed) have different nose colors, they must have inherited different combinations of the genes for nose color from their parents.

• Option A is wrong because puppies from the same parents can be related even if they have different traits.
• Option B is wrong because puppies of the same species (dogs in this case) have the same number of chromosomes.
• Option D is wrong because genes are inherited from both parents, not all from one parent (either mother or father).

Answer:

C. The pink - nosed puppy and the black - nosed puppy inherited different combinations of the genes for nose color from their parents.
