Genetics at a Glance
Paralives uses a sophisticated genetics system that determines what physical traits children inherit from their parents. Understanding this system is essential for players who want to plan their families across generations. The system uses a combination of dominant/recessive gene mechanics (for colors) and full-feature inheritance (for slider-based traits like facial features).
Important: Genetics Are Locked at Creation
Once a Parafolk is created in the Paramaker, their genetic code is permanently locked. Changing hair color later via a mirror only affects appearance — not the genetic color they'll pass to children. Always review genetic traits before starting a family.

What Gets Passed Down (Genetic)
| Trait | Inheritance Type | Notes |
|---|---|---|
| Height | Range-based | Child falls within parent's height range |
| Facial Features | Full-feature (50/50 per feature) | Entire slider set from one parent per feature |
| Skin Color | Dominant/Recessive | Brightness range from parents |
| Hair Color | Dominant/Recessive | Can skip generations |
| Eye Color | Dominant/Recessive | Can skip generations |
| Hair Texture | Dominant-most-wins | Coily > Curly > Wavy > Straight |
| Skin Details (freckles) | Dominant/Recessive | Can skip generations |
Color Genetics: Dominant vs Recessive
For color-based traits (skin, hair, eyes), Paralives uses a classic dominant/recessive gene system:
- Dominant genes show up more frequently and can mask recessive ones
- Recessive genes can hide for generations before reappearing in grandchildren
- A child receives two gene copies — one from each parent — and the dominant one is expressed
- Two recessive copies will show the recessive trait even if neither parent displays it
This means a child can inherit their grandparent's eye color even if neither parent has that color visible — the recessive gene was carried silently by both parents.
Example: If Parent A has brown eyes (dominant, B) carrying a hidden blue gene (recessive, b), and Parent B has brown eyes (dominant, B) also carrying a hidden blue gene (b), their child has a 25% chance of having blue eyes (bb) even though both parents have brown eyes.
Slider-Based Inheritance
For slider-based traits like facial features, genetics work differently from colors:
For each slider-based feature (nose shape, chin, cheekbones, etc.), the game selects one parent's entire slider set at random. It's not a blend — it's a binary choice:
- Child's nose = either Parent A's nose OR Parent B's nose (50/50 chance)
- Child's eyes = either Parent A's eyes OR Parent B's eyes
- Child's chin = either Parent A's chin OR Parent B's chin
This keeps each feature coherent rather than producing strange hybrid slider values. A child either has Mom's nose or Dad's nose — not a nose that's halfway between both.
Important: You cannot preview a child's slider-based genetics before birth. The game's genetic lottery is deterministic once the child is conceived, but there's no "preview genetics" option. Plan accordingly by ensuring both parents have features you're happy with.
Hair Texture Genetics
Hair texture follows a strict dominant-most-wins hierarchy:
Coily (most dominant) > Curly > Wavy > Straight (least dominant)
If one parent has coily hair and the other has straight, the child will likely have coily or curly hair. The dominant-most texture wins. If both parents have the same texture, the child will inherit that texture with high probability.
Unnatural Colors Warning
Paralives allows you to create Parafolks with unnatural colors — neon hair, purple skin, blue eyes, and other fantasy appearances. These unnatural colors will NOT pass genetically to children.
When the game generates a child, it silently replaces any unnatural parent colors with random natural colors before applying the genetic lottery. There's no way to preview or control what this "silent replacement" will be.
Consequence: If you create a neon-pink-haired character with unnatural genetics, their children will have natural hair colors — and those natural colors are determined by the game's hidden genetic calculations. You cannot force unnatural colors to pass to children.
3-Generation Planning
For players who want to engineer their family's appearance across generations, here's a 3-generation strategy:
- Generation 1 (Founding): Choose parents with similar physical traits and dominant genes you want to propagate. Document which recessive genes each parent carries.
- Generation 2: Select children with the traits you want to emphasize. Cross children from Generation 1 with each other or with carefully selected townies to strengthen dominant traits.
- Generation 3: By this generation, you can predict genetic outcomes with reasonable accuracy. Choose grandchildren who express the recessive traits you carefully preserved from Generation 1.
Theory: To make a recessive trait dominant in your family line, you need both parents to carry that recessive gene (even if hidden). Once you get a child who visibly expresses the recessive trait, they will pass it to all their children when paired with someone without that gene.
Strategic Tips
- Match parents for predictable results: Two parents with similar features produce more predictable children
- Study recessive carriers: If both parents have visible traits but carry hidden recessives, those recessives will appear occasionally in children
- Use townies strategically: Introduce external genetics by having children with diverse town NPCs to expand your family's genetic variety
- Document your bloodlines: Keep notes on which traits each family member carries — the game doesn't provide a genetics view, so personal tracking is essential
- Accept surprises: Part of the joy of genetics is the unexpected. Some of the most memorable family moments come from children who look completely different from their parents
