Breeders marking "het somthing" with no %
I mark mine as exactly what they are down to 50%. So I say they are 100% het, or 66% possible het, or 50% possible het..
This way there can be no confusion. I always put possible het after the percentage if it is not 100%.
Of course you'll always get inquiries that ask the details on the percentage if they don't read the add properly, or if they are confused about recessives in general.
