Cas show it as a human but it is the son of a spell caster (4th generation) and a vampire, You should be able to acess the vampire perk menu but not the spellcaster's, but if for some reason its the oposited for you he already have sun resistence so no worries on that, his dark form is totally linked to his human form. if you make him have a baby and it is red head, well it will be red as a toddle, brown as a kid, and green as a teen no clue why. #hybrid
