Broken Pattern Oddities[edit | edit source]
- Occasionally, a rabbit may present with a single random white spot (e.g., on the foot). While injury is a likely cause in many cases, the broken gene can sometimes be expressed so subtly that only one hair appears white.
- Key points about Broken patterns:
* Broken is **not** a white rabbit with black patches; it is a **solid-colored rabbit with a white overlay**. * White is a stripping effect caused by genes that block or dilute the density of eumelanin and pheomelanin. * To confirm a rabbit is genetically broken, **test breeding** is required.
- Genes and combinations that can produce broken patterns, random spotting, or “leakage”:
* `En` – Broken * `aachdchd` – Self homozygous Chinchilla * `v` – Vienna * `duw, dud` – Dutch variants * Chimera / somatic gene mutation – genes copied incorrectly during cell division
