Use this page to determine how many offspring the parents should have.
Single means one child is born.
MZ twins are monozygotic (identical) twins. The twin gene will not affect the likelihood that parents will have an MZ twin, but the Super Fertility [b] power will.
DZ twins are dizygotic (non-identical) twins. Both the twin gene and Super Fertility [b] will increase the likelihood of DZ twins. It is possible for DZ twins to have two different fathers.
Triplets are three non-identical children. Both the twin gene and Super Fertility [b] will increase the likelihood of triplets. It is possible for triplets to have two or even three different fathers.
Higher multiple births are between 4-8 offspring and can only occur with a Multiple Birth or Litter item.
If a parent is themselves a twin, triplet or higher birth, they
automatically carry the twin gene.
Use the table below to determine how many offspring the parents should have. Look up one parent down the side and the other parent across the top, then follow the table like a multiplication table to find your result.

If one or both of the parents carries the twin gene, use the table below to determine whether the offspring also has the twin gene. If a child is themselves a twin, triplet or higher birth, they
automatically carry the twin gene.
