MetaQTL can also used a trait ontology in order to group the QTL in trait categories which refer to the same genetic determinism. The ontology representation handles by MetaQTL is based on a simple hierarchy (such as in taxonomy) where each child has a uniq parent. The table which stores the trait ontology is defined by the following fields:
Term_id Term_name Parent_id Synonyms Definition 1 my_ontology 2 yield 1 3 dry_grain_yield_ear 2 4 dry_grain_yield 2 5 grain_yield 2 6 kernel_weight_per_ear 2 |
