Phenotype is:

Phenotype is:

• A. Physical, visual manifestation of genes
• B. The DNA sequence of a gene
• C. The set of alleles present
• D. The location of a gene

Answer: (A)

Phenotype is what you can observe about an organism—the outward expression of its genes. It includes traits you can see or measure, like eye color, height, flower color, or leaf shape, and it can be influenced by the environment as well as genetics (nutrition, climate, etc.). The DNA sequence of a gene and the set of alleles present describe the genetic makeup, or genotype, not the visible traits. The location of a gene refers to where it sits on a chromosome. So the phenotype matches the observable, physical expression of genes.
