How it works
1
Add clones
Enter one clone per line.
2
Set target genes
Choose your G/Y/H goal or use a preset.
3
Calculate route
Compare GEN.1 and GEN.2 route options by exact chance.
Rust Genetics Calculator
Calculate exact Rust crossbreeding routes in seconds. Find the best clone combinations for hemp, berries, and god clones with clear GEN.1 / GEN.2 outcomes.
A Rust Gene Calculator and Route Builder for faster breeding decisions. Add your clones, set a target, and get the best path with visible chances and clean route logic.
- Exact target chance for every route
- GEN.1 and GEN.2 paths side by side
- Works for hemp, berries, and god clones
Exact tie logic Multi-generation routes Target-based breeding
Sample route result
Sample input clones
XYGYXW, YHGGYX, XGGWGY, WGHXGW
Target
G:3, Y:3, H:0 (W=0, X=0)
Example route
- GEN.1: choose a clean center with low X/W pressure.
- Use donors that reinforce G/Y in key slots.
- Promote routes with stable center behavior.

How to read results
- GEN.1 = one breeding cycle recipe.
- GEN.2 = intermediate clone + final step.
- Chance = exact target hit probability with no W/X.
Add at least 4 clones and click "Find best route" to see possible combinations.

Use cases
Hemp clones
Plan high-throughput hemp routes with cleaner donor pressure.
Berry farming
Build stable berry genetics for predictable production cycles.
God clone planning
Use staged routes instead of one risky all-in attempt.
General crossbreeding
Turn messy clone lists into clear next actions.
Why this tool works
- Faster than trial-and-error breeding.
- Transparent slot math with visible probabilities.

Frequently asked questions
What is the best god clone in Rust?
A common god clone goal is a clone with only positive genes and no red genes, but the best target still depends on whether you want maximum yield, faster growth, or easier route stability.
How do tie genes work in Rust genetics?
When multiple surrounding genes have equal strength in the same slot, the outcome can split between them. This calculator shows those probabilities and builds routes around them.
Can I use this calculator for berries?
Yes. The same route logic works for berry genetics, and you can choose targets based on yield, growth speed, or more balanced farming setups.
How do I get 3G3Y in Rust?
Set 3G3Y as your target, add your available clones, and compare the best GEN.1 / GEN.2 routes. In many cases, a staged route is safer than forcing the target in one pass.
What is the difference between a stable clone and a god clone?
A stable clone is easier to reproduce and maintain consistently. A god clone is a stronger end-state target, but it often needs cleaner donors, better routes, and more setup discipline.
