(Genotype Of Individual Enumeration ORG GENE) means that ORG, an instance of organism, has among its genes GENE, an instance of information encoded by some particular gene. In practice, the genotype of an individual is a recording of the allelic repartition of genes as they differ from the type of reference. There will often be a genotype of reference for a type of organism, and genotypes of individuals will consist in the listing of variations with respect to that genotype of reference.
