Quizplus · Accepted Answer

Polygenic effects refer to the influence of multiple genes on a single trait, such as skin color. Therefore, the slight variations in skin color seen in the Smith children are likely the result of polygenic effects. Single genotype expression (A) refers to a single gene determining a trait, which is not the case for skin color. Cell division (B) refers to the process of cells dividing and replicating their genetic material, which does not directly influence variations in skin color. Dominant gene effects (D) refer to the expression of dominant genes over recessive genes, which also does not explain the variations in skin color seen in the Smith children.
