Polygenic inheritance refers to:

Genes carried by sex chromosome
Having different alleles for a trait
Traits controlled by more than one gene
Traits from both alleles being expressed in phenotype of offspring

The correct answer is: Traits controlled by more than one gene

Polygenic inheritance refers to traits that are controlled by more than one gene. This means that multiple genes contribute to the expression of a single trait. Option A is incorrect because genes carried by sex chromosomes refer to the mode of inheritance, not the type (polygenic vs. monogenic). Option B is incorrect because having different alleles for a trait does not necessarily mean that the trait is controlled by multiple genes. Option D is incorrect because the expression of traits from both alleles is known as codominance or incomplete dominance, not polygenic inheritance.
