Can two vampire sims have a human baby?

Published in Sims 4 Vampires 2 mins read

No, if two vampire Sims conceive a child in The Sims 4, their offspring will always be a vampire. There is no possibility for two vampire parents to have a human baby.

Understanding Vampire Heredity in The Sims 4

The genetics of vampirism in The Sims 4 operate with specific rules, ensuring that the supernatural lineage is consistent when both parents share the same life state. Here's a breakdown of how vampire inheritance works:
  • Two Vampire Parents: When both parents are vampires at the time of conception, the child is guaranteed to be born a vampire. This means the human trait cannot be inherited in this scenario.
  • One Vampire, One Human Parent: If only one parent is a vampire and the other is human, the outcome is less predictable. In this case, there's an equal chance – a 50/50 probability – that the baby will be born either a vampire or a human.
  • Two Human Parents: As expected, children born to two human parents will always be human.

Summary of Vampire Inheritance Chances

The table below summarizes the possible outcomes based on the parents' life states:

Human Human Guaranteed Human

What Happens if a Child is Born Human?

If a child is born human from a mixed-species couple (one vampire, one human), they will remain human through their infant, toddler, and child life stages. A human Sim cannot be transformed into a vampire until they reach their **Teenage years**. At that point, an existing vampire Sim can offer to turn them, allowing them to gain vampiric abilities and traits.
