A transitivity example. In the case of the term leptotene (GO:0000237), which is originally only linked to the terms cell cycle phase (GO:0022403) via an is_a relation and meiotic prophase I (GO:0007128) via a part_of relation, the following implicit relations are added: leptotene is_a biological_process (GO:0008150), leptotene is_a cellular process (GO:0009987), leptotene is_a cell cycle process (GO:0022402), leptotene is_a cell cycle phase (GO:0022403), leptotene part_of meiosis (GO:0007126), leptotene part_of meiosis I (GO:0007127), leptotene part_of meiotic prophase I (GO:0007128), leptotene part_of meiotic cell cycle (GO:0051321) and leptotene part_of M phase of meiotic cell cycle (GO:0051327).
