In genetic terms, what is a physical trait coded by genes referred to as?

• A. Phenotype
• B. Genotype
• C. Allele
• D. Gamete

Answer: (A)

A physical trait coded by genes is referred to as a phenotype. The phenotype encompasses the observable characteristics of an organism, which result from the interaction of its genotype— the genetic makeup— with the environment. For example, traits such as height, eye color, and flower color in plants demonstrate phenotypes that are influenced by the organism's genetic code. While the genotype represents the specific alleles or genetic information an organism carries, the phenotype is the manifestation of those genes in a recognizable form. Alleles are different forms of a gene that can contribute to an organism's traits, while gametes are the reproductive cells that combine during fertilization, carrying the genetic material but not directly representing physical traits. Thus, phenotype is the correct term to describe the physical expression of genetic information.
