Genotypic Data Model. The entity–relationship diagram describes the relevant sections of the Chado schema for storage of genotypic data. The genotype_call table (highlighted in orange) is a backward-compatible enhancement to the Chado schema, whereas all the supporting tables match the generic Chado specification. The genotype_call table gathers together all the metadata for a genotypic data point into a single record through the use of foreign keys.
