For any group , the trivial subgroup and the whole group are both homomorph-containing.
NO: This subgroup property is not transitive: a subgroup with this property in a subgroup with this property, need not have the property in the whole group

We can have subgroups such that is a homomorph-containing subgroup of and is a homomorph-containing subgroup of but is not a homomorph-containing subgroup of . For full proof, refer: Homomorph-containment is not transitive
Intermediate subgroup condition
YES: This subgroup property satisfies the intermediate subgroup condition: if a subgroup has the property in the whole group, it has the property in every intermediate subgroup.
