## Overview

Genes are DOL's core data abstraction - similar to structs or classes in other languages, but with built-in ontological semantics. A Gene defines an entity with properties (using `has`) and behaviors.

### Gene Syntax

```dol
gene <domain>.<name> {
    <entity> has <property>
    <entity> has <property>: <type>
}
```

## Gene Feature Status

| Feature | Status | Notes |
|---------|--------|-------|
| Gene declaration | WORKING | `gene name { }` |
| Entity properties | WORKING | `entity has property` |
| Typed properties | WORKING | `entity has property: Type` |
| Exegesis docs | WORKING | Full documentation support |
| Parse to AST | WORKING | Complete |
| Validate | WORKING | Semantic checks pass |
| WASM compile | NOT YET | Requires struct lowering |

---

## WASM Status

Genes do not currently compile to WASM. The error when attempting:

```
WasmError: Only function declarations can be compiled to WASM
```

**Roadmap:** Gene WASM support requires implementing struct layouts and memory management in the WASM backend.
