genotype
—genotypic /jen'euh tip"ik, jee'neuh-/, genotypical, adj. —genotypically, adv.
/jen"euh tuyp', jee"neuh-/, n. Genetics.
1. the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
2. the sum total of genes transmitted from parent to offspring. Cf. phenotype.
[ < G Genotypus (1909); see GENE, -O-, -TYPE]

Genetic makeup of an organism.

The genotype determines the hereditary potentials and limitations of an individual. Among organisms that reproduce sexually, an individual's genotype comprises the entire complex of genes inherited from both parents. Sexual reproduction guarantees that each individual has a unique genotype, except for identical twins, who come from the same fertilized egg. See also phenotype, variation.

      the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individual's genotype comprises the entire complex of genes inherited from both parents. It can be demonstrated mathematically that sexual reproduction virtually guarantees that each individual will have a unique genotype (except for those individuals, such as identical twins, who are derived from the same fertilized egg).

      The actual appearance and behaviour of the individual—i.e., the individual's phenotype (q.v.)—is determined by the dominance relationships of the alleles that make up the genotype, along with environmental influences.
