>Can you create a daughter copy of your project, for development purposes, then have bug fixes from the production copy feed to the daughter development copy, BUT NOT have changed to the daughter development copy feed back to the production copy of the project. In other words, I just want the changes to feed in one direction, from production to development, but not vice versa.

Yes, but why? It should be the opposite. Typically fixes are done in development and promoted to production after test. We keep projects in three stages Dev - Test - Prod, in that order. We use version pinning to control the flow of development.
