The physical traits that result from the genotype and the environment are called what?

• A. Genotype
• B. Allele
• C. Phenotype
• D. Food web

Answer: (C)

Physical traits you can observe, like eye color, height, or leaf shape, are called phenotypes. These arise from the genetic instructions you inherit (the genotype) and how those instructions are expressed in real life through environmental factors such as nutrition, climate, and exposure. The environment can influence how strongly genes express themselves, so the phenotype is the visible outcome of both genes and environment working together. For example, a plant might have the genetic potential to be tall, but poor soil or lack of water can limit its height; skin color can be influenced by genes but darkens with sun exposure. The genotype, by contrast, is the actual set of genes someone carries, not the outward trait; an allele is a variant form of a gene; and a food web is a picture of feeding relationships in an ecosystem, not an individual trait.
