Explain genotype and phenotype.

Explain genotype and phenotype.

• A. Genotype is the genetic makeup; phenotype is the expression of that makeup through physical and behavioral characteristics.
• B. Genotype is the expressed traits; phenotype is the inherited makeup.
• C. Genotype and phenotype are the same.
• D. Phenotype is the genetic makeup; genotype is expressed traits.

Answer: (A)

Genotype vs phenotype describe the inside genetic makeup and the outside expression of traits. Genotype is the genetic makeup—the specific alleles an organism carries in its DNA. Phenotype is what you can observe or measure—the physical form, traits, and even some behaviors that result from how those genes are expressed in a given environment. The genotype provides a potential set of traits, while the phenotype is the realized outcome, influenced by environmental factors like nutrition, temperature, or stress. For example, two plants might share the same genotype for a height-related gene, but one grows taller if given more light and nutrients, showing a taller phenotype. Dominance relationships can also hide or reveal traits in the phenotype depending on which alleles are present. The key distinction is that genotype is the inherited genetic information, and phenotype is the observable expression of that information.
