⚠️About Version 1.0.0

1.0.0 is a test version that is not recommended for playing. It may give you a poor gameplay experience.

In version 1.0.0:

① All vanilla wheat and grass drop gametes/hybrid seeds. This breaks many vanilla mechanics; for example, farmer villagers cannot plant.

② Hybrid crops cannot be composted.

③ Many remaining minor defects and bugs.

Please use version 1.1.0 or later.

Crossbreeding

Bring Mendelian genetics into Minecraft. Every wheat plant has its own genome — breed, cross, and cultivate your own super wheat.

Quick Start

1. Break grass → 50% chance to drop a crossbreeding seed
2. Plant → on farmland, just like vanilla wheat
3. Inspect → hold a stone hoe and right-click a mature plant
4. Harvest → break mature wheat to get crossbreeding wheat + 4–6 gametes
5. Cross → craft 1 female gamete + 1 male gamete → new seed
6. Bake → craft bread from crossbreeding wheat; quality depends on genes

Note: Vanilla wheat and vanilla seeds are unaffected. Only grass drops and crossbreeding crops produce the new items.

Genetics Basics

Each wheat has 6 gene pairs, written as 12 characters, e.g. AaBbccDdEeFF.

• Uppercase = dominant, lowercase = recessive
• A pair shows the dominant trait if at least one uppercase allele is present
• A pair shows the recessive trait only if both alleles are lowercase

Gene Reference

Bold = the "good" trait. A, B, F good traits are dominant; C, D, E good traits are recessive.

Trait Effects

Bread Crafting

All input wheat must satisfy the requirement, otherwise you get plain bread.

Count is determined by the first wheat: thin husk (ee) uses 1, thick husk (E_) uses 3.

Inspect with Stone Hoe

Hold a stone hoe and right-click a mature plant. Chat shows:

位于（10，64，20）的小麦
表型：多穗、抗病、高饱食、高饱和、多壳、生长旺盛

Click the message to copy it to your clipboard (in simple mode, the genotype is included).

Simple Mode

Requires OP level ≥ 2:

/crossbreeding simple true    enable
/crossbreeding simple false   disable

When enabled:

• Stone hoe right-click also shows the genotype
• Gametes, seeds, and wheat show genotype in tooltips
• Click-to-copy includes the genotype

State is saved per-world.

Gene Debug Stick (Creative only)

Obtain: Creative "Op Blocks" tab, or /give @s crossbreeding:gene_debug_stick.

Usage:

1. Hold the stick
2. Left-click: cycle the gene locus Aa → Bb → Cc → Dd → Ee → Ff → Aa
3. Right-click a crossbreeding crop: cycle the pair AA → Aa → aa

The current state briefly appears above the hotbar.
