Genotype and phenotype are both terms commonly used in the field of genetics since they are used to understand inheritance patterns and the expression of traits in organisms. They are also both affected by environmental factors. Environmental factors such as nutrition, exposure to toxins, and lifestyle, can influence the expression of genes and thus impact the phenotype. Environmental influences can modify or alter the expression of genes of the genotype, leading to variations in observable traits. Both are also characteristics of living organisms. Genotype represents the genetic makeup, while phenotype represents the observable traits of an organism, such as height.
