The genetic make-up of an organism is described as

The genetic make-up of an organism is described as its genotype. Genotype refers to the complete set of genes and genetic material that an organism inherits from its parents. This includes both the dominant and recessive genes, and determines the genetic traits and characteristics of the organism. For example, a person's genotype determines things like their eye color, hair color, and height, as well as their susceptibility to certain diseases or conditions. While some genetic traits may be visible, such as eye color or hair color, many others are not visible to the naked eye. Allele refers to a variant form of a gene that codes for a specific trait. Chromosomes are structures that contain DNA and are located in the nucleus of a cell. Phenotype refers to the observable physical or biochemical traits of an organism, which are determined by both the genotype and environmental factors.
