What term describes observable traits resulting from the interaction of genotype and environment?

• A. Phenotype
• B. Genotype
• C. Genome
• D. Heritability

Answer: (A)

Observable traits produced by how genetic instructions are expressed in a given environment are called the phenotype. The genotype provides the genetic potential, while environmental factors—nutrition, climate, learning experiences, social conditions, and more—shape how those genes are expressed. Together, they determine traits we can see or measure, like height, skin color, or behavior. The genome is the full genetic material, and genotype refers to the individual’s genetic makeup. Heritability is a population statistic describing how much of trait variation is due to genetic differences, not the trait itself.
