The phenotype of an animal typically does not depend on a) the genotypes of the parents. b) seasonal changes in the environment. c) the source of the animal's food. d) how genes of the animal are expressed.

The correct answer is-

C) The source of the animal's food.

Phenotype of an organism can be described as the physical characteristics or traits that the individual possesses ( such as hair color, eye color, skin color).

It is depicted by the genetic makeup ( that is genes) of the organism that is inherited from parents and is also influenced by some environmental factors.

Thus, it does not depend on the source of the animal's food.

Therefore, option C) is the right answer.
