What happens when your alien sim and vampire sim have children

[kimberlyp2002]

well I had an alien get pregnant to a normal sim who had no vampire blood and the baby was born a vampire. female alien + normal male = vampire what?

[jpkarlsen]

Do you have any mods installed?

Was the Vampire baby conceived or born on a Lot that has the "On a Dark Ley Line" Trait? Vampire babies can randomly occur because of that, even when no Vampires are present. By the way, concerning the main topic, Aliens can only have full Alien babies with other Aliens. With a Human, it will be a Hybrid with few powers and no access to a disguise. With a Vampire, it will only be a Vampire. If it try to make an Alien a Vampire with a cheat, it will bug out. The code isn't set up for both Life States to exist in the same Sim.

Bottom line...

Alien + Alien = Alien

Alien + Human = Hybrid

Alien + Vampire = Vampire (or possibly Alien/Human Hybrid)

Human + Vampire = Human or Vampire (random chance)

@LBonne24, @Behappy1st, @iamsweetmystery, I was just coming here to tell you guys my findings in the game! LOL   

I made a married couple with a husband who is an Alien and a wife who is a Vampire.  Their fist child must be a human/Alien hybrid because from infancy he had an Alien voice, and in CAS when I went to select outfits for it to wear when he became a toddler, it had the Alien face above the personality area of CAS. He also has a human disguise!   I don't know of any powers yet since he is just a toddler.   (Also as an infant, the mother had an interaction that said "It's so .., cute?"   ) So far, if I didn't know any better I would say he inherited the Alien life-state, but apparently he is an Alien/human hybrid. 

Their second child appeared to be human (normal voice and no "it's so … cute?" interaction, but upon becoming a toddler, it was shown yet again in CAS when picking out clothing that the child is a Vampire! 

I did not choose the "On a Dark Ley" attribute to the house so I wouldn't skew the results! But I did choose the "On a Ley Line" attribute to try to get as many offspring as I could from this paring! :eahigh_file:  (Sadly, both pregnancies only resulted in singletons so far ). Here are some pictures:

The son was pure Alien. A hybrid would have voice and/or skin tone as an alien but not the disguise. The latter is alien only and all aliens have that.

@jpkarlsen, (as well as @kimberlyp2002, @iamsweetmystery, and @Behappy1st)  I now agree!  I thought it seemed odd he had the Alien denotation in CAS, as well as the disguise, but then just now I was playing that family and saw that his Plumbob had the silver Alien ring around it.  So I was just coming back here to update my findings and saw your post confirming my suspicions!   So apparently a full Alien parent can have a fully Alien child even if the other parent is not Alien.   Thanks for the clarification!

Awesome @PugLove888! Good that you tested it out.

[Behappy1st]

I went back to my game and discovered when I made my Alien I made her look human in Alien form. I must have thought I was making the human side of her. Than I was pulled away from playing for a while and went back, downloaded my vampire and Alien and started playing not knowing I never finished doing her so her Alien and Human form are the same..They had twin girls, one a vampire and one who I believe is human. When she aged up to toddler no Alien and no Vampire sign. Went to CAS mom is Alien, dad is Vampire sister is vampire and she still shows as Human. I did a save as so I could age her up to teen to see what happens without messing with my game, She still shows as human.

Oh, I forgot to mention I shared them to the gallery if you want to see for yourself there name is Sheridan.

[PugLove888]

@Phantomlover1717, thank you ! 

@Behappy1st, I found the Sheridan family in the Gallery!  I downloaded them but haven't played them yet.  I saw that one of the daughters is Human, the other Vampire, and the toddler boy is Alien.  Perhaps since Vampirism can be cured, the base for a Vampire is a Human?   That would account for having one daughter be human, but this is just a hypothesis.   Thanks for contributing to this fascinating topic of Sim genetics! :eahigh_file:  I will try to play your family this week but I doubt I can get much from the human teen since I can't see into the game mechanics.   The Human girl can either be upset that she didn't get a special ability like her siblings, or she can be grateful that she is "normal" like her friends! 

@kimberlyp2002, Mods can change this (which is why @jpkarlsen asked if you used them ).  If you don't use Mods, then go into Build/Buy Mode and look in the upper left corner of the screen there is an icon that looks like a house with an "I" in side it.  Click on that and it will show you the Lot Attributes (which you can change, add to, or subtract any you want).  If you have the attribute called "On a Dark Ley" you will be likely to get Vampire babies, even if both parents are Human!   This would be the only way I know of getting a Vampire baby if neither parent is a Vampire if you don't have any Mods! 

Happy Simming!
