The logic behind this query sounds quite odd but see below something that might work.

{
  var(func: eq(name, 'boss')) {
     Q as <~Child>
  }
    
  data(func: uid(Q)) {
    uid
  }
}

For more Cypher to DQL see

This in Dgraph is quite complicated.

By logic it would be something like

{
  var(func: has(Child)) @filter(has(<~Child>)){
     p as uid
     q as Child
  }
    
  data_p(func: uid(p)) {
    uid
  }
  data_q(func: uid(q)) {
    uid
  }
}

But in a Dgraph perspective this is odd and very expensive to do and you have to use reverse edges indexing. Dgraph is very different from Neo4j.
