The appropriate answer to the question about the genetic makeup of an organism is genotype.

Explanation

The term genotype refers specifically to the genetic constitution of an organism; it includes all the alleles that an organism carries for a particular trait. Essentially, the genotype determines potential traits and characteristics of that organism. On the other hand, phenotype refers to the observable physical and physiological traits of an organism, which are the manifestation of the genotype in combination with environmental influences. For example, in pea plants, the genotype could be "Tt" (heterozygous for tallness), while the phenotype would be expressed traits such as height, seed color, and flower shape. Thus, while the genotype is the genetic foundation, the phenotype is how those genes express themselves in the organism's characteristics.
