If a person has blue eyes, this is an example of which concept?

Explanation:
Blue eyes describe a trait you can observe, so it’s a phenotype. The phenotype is what you see or measure—the visible trait produced by the genetic information in the body. The genotype would be the specific genetic instructions and alleles a person has for eye color, which determine which phenotype appears. An allele is a version of a gene, and a chromosome is a structure that carries many genes, including those related to eye color. So the blue eye color is the phenotype—the observable result of the underlying genotype.
