The genotype–phenotype map is a conceptual model in genetic architecture.

Coined in a 1991 paper by Pere Alberch,[1] it models the interdependency of genotype (an organism's full hereditary information) with phenotype (an organism's actual observed properties).

The map visualises a relationship between genotype & phenotype which, crucially:[2]
