I'm looking at a half paint/quarter horse mare for possible purchase. She has Impressive in her. I'm wondering exactly what questions I might need to ask about HYPP? I know I am looking for N/H, correct? I don't know what she is yet since I wanted to educate myself somewhat before inquiring about her.
Also, from what I understand, if a horse is N/H, this means the horse cannot pass on the trait but does this mean they will have no symptoms?
