Instantiating array of game objects can't get parent transform [Editor Scripting]

So I want to instantiate an array of game objects via editor scripting. Now the problem is when I instantiate the prefab, it loses its parent in the hierarchy. When I'm instantiating like the script below, it works just fine:

 for(int i = 0; i < 20; i++){ //_dTarget.halfLength; i++){
    GameObject a = (GameObject)PrefabUtility.InstantiatePrefab(_dTarget.wallTile);
    a.transform.parent = goTarget.transform;
}

but if I'm instantiating like this:

GameObject[] testG = new GameObject[20];
for(int i = 0; i < 20; i++){
    testG[i] = _dTarget.wallTile;
}
for(int i = 0; i < 20; i++){ //_dTarget.halfLength; i++){
    GameObject a = (GameObject)PrefabUtility.InstantiatePrefab(testG[i]);
    a.transform.parent = goTarget.transform;
}

they lost their parent and instantiated outside the parent:

Any ideas why this happens?

Before you can set the parent, you need to disconnect the new object from the prefab. You do this with PrefabUtility.DisconnectPrefabInstance.

Example:

for (int i = 0; i < 20; i++)
{
    GameObject a = (GameObject)PrefabUtility.InstantiatePrefab(testG[i]);
    PrefabUtility.DisconnectPrefabInstance(a);
    a.transform.parent = goTarget.transform;
}

Update: As of Unity 2018.3, DisconnectPrefabInstance is obsolete. PrefabUtility.UnpackPrefabInstance can be used instead.
