As I already said in my posting before this morning , I think it is VERY likely that martiou07 is right with his posting !

Because "...it would be likely to have happened more often in CsV allready, if they would have had the brown (bb) gene in them from the beginning." ( What Jennin Lauma told before.)

(Ok, it´s not 100 % sure that crossing with Saarloos is the reason - but close to this ! And much more likely than a spontanous mutation...or caused by inbreeding, like supposed by Saschia.)
