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.

Answers

Answer: 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.

Answer:

C) the source of the animal's food

Explanation:

Phenotype is an important concept adopted in genetics and is usually defined as the set of observable characteristics of an organism.

Thus, this set includes the morphological and physiological characteristics of an individual, defined through the expression of their genes and may be inherited from their predecessors.

However, it is important to stress that the phenotype is not only determined by genes, but also influenced by the environment in which an individual is inserted, such as climate change or random variations.

An animal's food source, however, does not necessarily influence an animal's phenotype.

Given these statements, it can be concluded that the correct alternative is C.
