Trait of Inheritance |
Chestnut is one of the major coat color variants in the horse and is characterized by an entire red coat lacking black or brown pigmentation.
Chestnut Coat Color is an inherited autosomal recessive trait. This means that a horse can be genetically clear (homozygous normal), affected, or a carrier (heterozygous). The carriers can spread the Chestnut Coat Color gene in the population. Therefore, reliable information on non-affected horses is the key for controlling. The Extension locus has two alternative states (alleles). The dominant allele E produces black pigment in the coat. The recessive allele e produces red pigment. Chestnut horses are homozygous e/e.

Description |
|
This is a mutation-based gene test, which offers many advantages over other methods
The genetic mutation which causes this trait has been identified. By DNA testing the responsible mutation can be shown directly. This method provides a very high accuracy test and can be done at any age. It offers the possibility to distinguish not only between affected and clear horses, but also to identify clinically healthy carriers. This is an essential information for controlling the disease in the breed as carriers are able to spread the disease in the population, but can not be identified by means of common laboratory diagnostic.

Sample Requirements |
Hair Sample from mane with roots (approx 30 hairs) , Buccal Swabs or 1 ml whole blood in EDTA tube.
How to obtain a viable hair sample
Pull around 30 hairs from the mane of the horse with the roots (in faols hair from the tail maybe taken). Wrap the hairs around your finger or a comb, as close as possible to the skin to ensure you obtain the hair roots. Keep dry, put in a bag, label the bag with the horse name, test (s) required.
