Which of the following best describes polygenetic inheritance?
A) An individual receives multiple alleles from more than two parents.
B) Characteristics resulting from polygenetic inheritance exhibit a wide variation in genotypic expression.
C) Characteristics resulting from polygenetic inheritance exhibit a wide variation in phenotypic expression.
D) Characteristics most commonly result in mutation.
Polygenetic Inheritance
Two or more genes contributing to the phenotypic expression of a single characteristic.
Genotypic Expression
The manifestation of characteristics or traits in an organism resulting from the interaction of its genetic makeup with the environment.
Phenotypic Expression
The observable physical or physiological traits of an organism, which result from the interaction of its genotype with the environment.

Final Answer :
C
Explanation :
Polygenetic inheritance refers to the inheritance of traits that are controlled by multiple genes. These traits often exhibit a wide variation in phenotypic expression, as each gene contributes to the final phenotype in a complex way. Examples of polygenetic traits include height, skin color, and intelligence. In contrast, answers A, B, and D do not accurately describe polygenetic inheritance.
