Just want to make sure, but you do know that to pass on traits level 2+, you need the other parent to have the same trait at most one level under, right? So to even have a chance to pass on potent III in the first place, you'd need the other parent to have potent III or II. For a child to inherit both potent III and nurturing III, you would need both parents to have potent III/nurturing III, or one with both level III and the other with both level II, or each with one at III and the other at II, etc.
