Hello, I'm not really sure where to post this.... Hope this is ok here.
I'm thinking of buying a mare. She is solid bay, three years old. Her owners refer to her as a 'grade', and seem to think she cannot be registered, as her Dam is AQHA, and her sire is APHA. What's up with this? I once owned a registered paint mare, and she also had an APHA sire, and AQHA dam. I thought the two registeries were somewhat interchangeable, with some variations in regards to color patterns; breeding stock registry, etc. Anyone have any knowledge on this subject?
