Which term describes the observable trait that results from the genotype?

Explanation:
The observable trait that comes from the genotype is called the phenotype. The genotype is the genetic makeup—the specific alleles an organism carries. The phenotype is how those genes are expressed in the organism, what you can see or measure, such as eye color, height, or leaf shape. Environment can influence how a trait shows up, but the phenotype is the visible result of the genotype. The other terms don’t fit: genotype refers to the genetic makeup itself, not the outward trait; a wave isn’t related to this concept; and genetic variation describes differences in DNA among individuals, not a single observable trait.
