Genetics Breeder
Calculate crossbreeding results, find optimal combinations
Plant Genetics in Rust
Every plant in Rust has 6 gene slots. Each slot contains one of 5 gene types. Through crossbreeding, you can combine plants to create "god clones" — plants with all positive genes.
Gene Types
Red genes (W, X) have weight 1.0 — much stronger than green genes at 0.6. You need 2 matching green genes to beat 1 red gene(0.6 + 0.6 = 1.2 > 1.0).
How Crossbreeding Works
Crossbreeding happens when a plant enters the crossbreed phase. The game resolves each of the 6 gene slots independently.
For each slot:
- Sum the weights of each gene type across all neighboring plants
- Find the gene type with the highest total weight
- Compare to the center plant's gene weight
- Donor wins only if strictly greater than center (equal = center keeps its gene)
- If multiple donors tie → 50/50 coin flip
Planter Layout
A large planter has a 3×3 grid. Plants only crossbreed with neighbors within the same planter (not across planters). Neighbors include horizontal, vertical, and diagonal.
Common God Clones
A "god clone" is any plant with 6 positive genes and zero red genes. Once you have one, you can clone it infinitely.
Tips
- •Use the center position (8 neighbors) for the seed you want to improve — it has the most influence.
- •Place 2+ copies of the same clone around the center to guarantee their green genes overpower red ones.
- •Use Smart mode in the calculator to automatically find the best combinations from your available clones.
- •Different plant types (hemp, berries, corn, etc.) use the same genetics system — but they don't crossbreed with each other.
- •Use the Scanner tab to automatically detect genes from your Rust game window — no manual typing needed.
- •Drag & drop clones from your list directly onto the planter grid for quick placement.
