Personally I find this easier to read. Unproven dominant is pretty much made up, but I feel it's necessary to differentiate.
Recessive Co-Dom/Incomplete Dom Dominant Unproven Dominant Heterozygous No Visible Change Visible Change Visible Change Visible Change Homozygous Visible Change Different Visible Change Same Visible Change ???
To the OP, there always a chance something unknown is lurking, by chances are very slim.
