|---|---|
| Fertility | -50% |
In play
Sterile: fertility falls by 50%. Sterile is the fertility collapse. Do not count on this character for the next child. Fecund is the opposite.
How to get Sterile
- Gain: Congenital (shown in game as Sterile): inherited from parents who have or carry Sterile (base 80% if both parents have it, 25% if only one does), and about 0.5% of children are born with it at random. It is also one of the defects inbreeding produces: children of related parents can be born with it, and a parent with Sterile makes the Inbred trait possible for children of a related couple.
- Remove or lose: Permanent for practical purposes: no treatment or decision removes it, and the character can still pass the trait on to children.
