As far as I can tell, 7 kids inherited Maewyn's blue skin, 6 inherited her blue eyes (including the last 4 kids), 8 inherited her blue hair, and all except Nerys (at the moment) inherited the freckles, though some only had a few while others had a lot, and some didn't show up until their teen years. And the Spellcaster trait is more dominant than the Mermaid trait but only sometimes more dominant than the Alien trait (Eira showed up as a full alien, Nerys was a hybrid so I had to cheat away her Spellcaster trait in order to see the disguise show up in CAS).
