What type of trait is characterized by a range of variation controlled by multiple genes?

• A. Sex-linked Trait
• B. Continuous Variation
• C. Monogenic Trait
• D. Dominant Trait

Answer: (B)

The type of trait that is characterized by a range of variation controlled by multiple genes is continuous variation. Continuous variation refers to traits that do not fall into distinct categories but instead show a spectrum of phenotypes. For example, height, skin color, and weight in humans are all influenced by the interaction of multiple genes as well as environmental factors. This results in a gradual range of variation rather than discrete categories. In contrast, traits that are classified as monogenic are influenced by a single gene, leading to a clear-cut phenotypic outcome. Sex-linked traits are those that are located on the sex chromosomes and have a specific inheritance pattern related to gender. Dominant traits, on the other hand, refer to specific traits that will express themselves in the phenotype even in the presence of a different allele, but they do not encompass the idea of continuous variation which involves multiple genes and a wide range of expressions.
