Glossary

Genotype is the genetic constitution of an organism. A mango seedling formed through fertilization has its own genetic combination, whereas a grafted scion normally preserves the genotype of its source tree. Genotype is distinct from phenotype, the characteristics actually observed under particular conditions. Poor flavor from immature fruit or weak growth in a saturated pot does not by itself demonstrate that a correctly labeled graft has changed genetically. Identity questions need provenance and, where appropriate, more specialized evidence.
