Which type of traits results from the interaction of multiple genes to produce a variety of phenotypes?

The correct answer is polygenic characters, which refers to traits that are influenced by multiple genes, each contributing to the overall phenotype. This genetic interplay results in a continuous range of phenotypes rather than discrete categories. Common examples include traits such as height, skin color, and weight in humans, where variations occur due to the cumulative effect of several genes.

Polygenic inheritance contrasts with other patterns of inheritance. Incomplete dominance involves a scenario where the phenotype is a blend of the two parental traits, but it does not stem from multiple genes affecting a single trait. Sex-linked traits are dictated by genes located on sex chromosomes and do not typically exhibit the broad range of variations that polygenic traits do. Codominance occurs when both alleles in a heterozygous organism are expressed equally, resulting in a phenotype that shows both traits distinctly rather than a range of phenotypes. Thus, polygenic characters are distinctly characterized by the variety of phenotypes generated from the interaction of multiple genes.
