What refers to the physical appearance of a trait?

Explanation:
Phenotype is the physical appearance of a trait. It’s the observable expression that comes from the organism’s genes and can be influenced by the environment, so you can see it as the trait you can measure or notice—like eye color, height, or flower color. The genotype is the genetic makeup—the actual genes an organism carries that could be expressed. The genome is the complete set of genetic material in an organism. An allele is a version of a gene, which can lead to different expressions of a trait. So when you’re asked about the physical appearance, the right term is phenotype.
