Reposting Sarahs screenshot with some things highlighted
So we have a RockJadite baby
Mum was a FlowerChild Lucy with a RockJadite Dad
Dad was a Genesis Sunflower with an Odyssey Sublime Dad, Odyssey Sublime is dominant to FlowerChild Lucy so can't have pulled the RockJadite, however the Odyssey Sublime does have a Magic Reef parent so that looks to be what pulled the RockJadite.
Of course we can't know for sure that Magic Reef is the hidden, the Magic Reef may hide something more recessive so we will have to wait for Amanda to pull the hid.
This however does appear to be a proof of RockJadite recessive to FlowerChild Lucy
The only other starters are on the Genesis Sunflower but since thats what passed the potential hidden there is moot as we know the Sunflower must hide Odyssey Sublime or more recessive.
It would be good to see actual pedigrees instead of a profiler screenshot as we get so much more information from pedigrees direct from KittyCats.
