I'm currently working on compiling a list of protein chains we know correlate to specific traits and will probably need to reach out to a few researchers. Certain aspects would simplify breeding if we could just map them. Also, as we discussed, cross-referencing those traits with others like growth and type... I know they already mapped the rabbit genome; I just don't have complete access to it yet to convert that information into a more understandable format. 
Planned tests aim to provide breeders with definitive genetic outcomes similar to tests available for horses and dogs.


rabbit genome map. So, there are several sections, but a test for white spot carriers would be a good early start.

It would have to look for Dutch, "dud, duw," Vienna, and English Spot En, at bare minimum. Because we have a few discrepancies popping up, we think they are due to intense modifiers making an extreme blanket pattern.

Other things I'm interested in seeing have any correlation is recessive genes' effect on immunity, the  Harlequin gene, and heat tolerance.
 
a genetic test  that breeders can use to help in selecting future stock. like you have for horses and dogs that give definitive genetic outcomes for coat patterns, as well as several hereditary disorders... so for rabbits it would be  coat geneone,  split penis carriers, malocusion carriers, mooneye,  ect.

Traits[edit | edit source]

Overview: Traits are not genes themselves, but modifiers that adjust the expression of certain genes. In rabbits, trait modifiers influence coat color, pattern, intensity, and other phenotypic characteristics. Understanding these modifiers can simplify selective breeding and predict outcomes in offspring.

Common Trait Modifiers[edit | edit source]

Intensity Marker[edit | edit source]

The intensity marker is typically seen in rabbits with a non-extension coat pattern (e.g., "red"). The intensity is usually noted as:

  • + : Palomino / creamy yellow
  • ++ : Light red
  • +++ : Medium red
  • ++++ : Dark mahogany red

This modifier affects the depth of color expression without changing the underlying genetic locus.

Broken Gene Extent (En – Broken)[edit | edit source]

The broken gene affects the amount and distribution of white on the rabbit's coat. Expression can range from minimal to nearly complete:

  • **Booted Broken:** Over 90% color, minimal white
  • **Blanket Broken:** 10–50% color with large white areas
  • **False Charlie:** Less than 10% color, rabbit appears almost entirely white

Modifiers can sometimes make genetically spotted rabbits appear solid due to extreme blanket patterns.

Genetic Testing for Traits[edit | edit source]

With the rabbit genome mapped ([NCBI GenBank: Oryctolagus cuniculus Thorbecke inbred](https://www.ncbi.nlm.nih.gov/nuccore/256946799)), breeders can begin to explore genetic tests for:

  • White spot carriers (Dutch, Vienna, English Spot)
  • Coat pattern predictions (e.g., Harlequin, En modifiers)
  • Hereditary disorders and recessive genes affecting immunity
  • Malocclusion carriers, moon eye, and other traits

Planned tests aim to provide breeders with definitive genetic outcomes similar to tests available for horses and dogs.

Research Resources[edit | edit source]

Note: Future work involves compiling a list of protein chains correlated with specific traits and cross-referencing them with growth, type, and environmental adaptations such as heat tolerance.
