Getting ancestor nodes in phenotype ontology

[ChristopherMancuso]

I was wondering how to go about getting ancestor nodes for phenotype terms like WBPhenotype:0001236 or HP:0001263. I don't really have useful code to put down.

One question is if I do a search like
https://api-v3.monarchinitiative.org/v3/api/association?object=HP%3A0001263&limit=20&offset=0
This will have a part of the response that has "object": "HP:0001263", and then a bunch of object closures. What exactly are these closures? Ancestor terms? Any related term? Both child and ancestor terms? Something completely different?

I ask this as if I can get genes directly related to some phenotypes, I would like to find the ancestor nodes so I can then propagate these gene annotations.

Thanks!
