I am pretty sure it is just a random trait. But, I have noticed that there seems to be alot het pied and possible het pieds that may display the ringer(from pics and info online). I have also noticed that some breeders sell the het pieds or possible het pieds for more if they are ringers.....Is that just another 'marker' for the het pied? will a possible het pied ringer always end up being het pied??
