Here is Dreampoetz chart inline so it's easier to see
Twilight mom
Galaxy Sun dad
Twilight baby
Will hide Galaxy Sun or more recessive
Galaxy Sun is recessive to Twilight. Right now based on prior evidence, it just needs to be proven dom or rec to Grotto to be placed.
Which makes me very interested in that Galaxy Sun dad. He has Galaxy Sun shown like his mom but his dad is Pewter shown. I would really like to know what Galaxy Sun dad hides. If it is Grotto, it would place it.
Do you think you might put Dad Sunshine Dawnriser against something more recessive than Grotto just to check what he has hid?
