Rust Genetics Calculator
Enter the six genes from nearby parent clones and predict each offspring slot using Rust crossbreeding weights.

Parent clones
Build the crossbreed
Use exactly six letters from G, Y, H, W, and X. Incomplete parents are ignored until all six slots are filled.
Target search
Find a one-cross combination
| Parents | Predicted | Matching slots | Result |
|---|---|---|---|
| #3 | GGGYYY | 6 / 6 | Exact |
| #1 | GGYYHH | 3 / 6 | Closest |
| #2 | YGYGHH | 1 / 6 | Closest |
Search checks every parent combination up to the selected limit and stops at the shortest exact result.
Predicted offspring
GGYYHH
Planning score: 10. G and Y favor production, H adds hardiness, while W and X reduce the score.
Weight reference
How each slot is resolved
| Gene | Meaning | Weight | Type |
|---|---|---|---|
| G | Growth | 0.6 | positive |
| Y | Yield | 0.6 | positive |
| H | Hardiness | 0.6 | positive |
| W | Water | 1 | negative |
| X | Empty | 1 | negative |
Quick answers
Frequently asked questions
Why can a predicted slot show a question mark?
A question mark means two or more genes have the same highest weight in that slot. The input does not produce one deterministic winner.
Why do W and X count more heavily?
Crossbreeding uses stronger weight for red genes. One red gene can outweigh one green gene, so parent placement matters slot by slot.
Does target search plan multiple generations?
No. It searches deterministic one-cross combinations from the clones entered above. Multi-generation planning needs verified inheritance and placement rules beyond this weight model.
