The colour pearl has caused me much confusion in the past. This animal just kinda showed up in the holder bin and looked different so I held her back. After raising her up and breeding her she proved co-dominant. I then attemped to see if there was a super so I bred one of her pearl sons back to her. I tried several of the same pairings and the litters where exteremly small. I did some research and discovered that the Pearl gene is lethal in it's homozogous state. The litters were small because half perished.
