Rabbit genetic testing
Research actively in progress
Little Haven DNA is expanding into rabbit genetics with a strong focus on accuracy, validation, and real breeder outcomes. This page explains what we are building, how the development process works, and what to expect while research is underway.
What this program is
This rabbit genetics project is a research and development effort focused on creating DNA tests that are useful to breeders. Useful means the results match real breeding outcomes, stand up to repeat testing, and are interpreted clearly.
I am an active rabbit breeder and exhibitor, showing in ARBA sanctioned shows across the state of Florida. My primary focus is Netherland Dwarfs, and I am building both breeding and research lines with long term goals that include ARBA Convention in 2027.
We are working with a geneticist to design and validate assays for specific genes. Each gene must be validated with known animals before it is offered publicly.
How the development process works
1. Define the trait and the goal
We start by defining what the test should answer for breeders. Examples include carrier status versus visual expression, and how many copies matter for the trait.
2. Find candidate DNA markers
The geneticist identifies candidate variants or genomic regions linked to the trait. Not every trait has one simple variant, and some require more work to pinpoint reliably.
3. Build an assay and test it internally
We design an assay to detect the marker consistently. We run repeat checks to confirm the assay is stable, readable, and not overly sensitive to sample quality.
4. Validate using known animals
Validation means comparing DNA results to rabbits with known genetics. Known can mean documented lineage, confirmed genotype, or repeated breeder outcomes that strongly support genotype.
5. Expand validation across lines
A test must work across multiple unrelated lines, not just one rabbitry. This step helps reduce false confidence from line specific markers.
6. Release with clear interpretation
When the evidence is strong enough, we publish the test with clear result wording and breeder focused explanations. Anything not proven stays labeled as in development.
Timeline note: because validation depends on sample availability and confirmed genetics, we cannot promise a release date. The goal is to release only when the data supports it.
Genes currently in development
Initial development focuses on traits that matter most to breeders and exhibitors, especially traits that impact planning and selection.
- Wooly gene
- Vienna gene
- Wide band gene
- C locus
- E locus
Additional genes will be added as assays are validated and confidence is built through real world outcomes.
What we need from the rabbit community
The biggest factor in development speed is access to strong validation samples. For validation, unknown or guessed carriers cannot be used. We need rabbits with genetics that are already confirmed as much as possible.
- Rabbits that are known visual for the trait
- Rabbits that are known non carriers in lines where the trait has been thoroughly tested out
- Rabbits with clear breeding history that supports genotype
- Unrelated lines are especially valuable
If you are not sure whether your rabbit counts as known for validation, reach out. We would rather review the details first than collect unusable samples.
Sample types needed
Sample quality matters. Clean samples improve the odds of a successful extraction and help reduce repeat work. If you are mailing multiple rabbits, label everything clearly.
- Hair samples pulled from the root with the white follicle attached
- Blood samples as a small drop on paper, coffee filter, or a swab
