A black or brown/bay coat colour can only arise if a horse is either a non-carrier (E/E) or a carrier (E/e) for the red coat colour. The Agouti gene determines whether the horse develops a black or a brown coat. A horse homozygous for the recessive allele of the Agouti gene (a/a) is black. In a carrier or non-carrier horse (A/a or A/A), the black pigment appears only in certain areas like mane or tail and the horse is brown/bay. The colour inheritance for specific pairings follows the same rules as described for the red factor. For breeding purposes, the Agouti gene is mainly important as a “hidden” feature in red coloured horses.
1-2 weeks after arrival of the sample in the lab
The DNA test is performed out of EDTA blood or or 20-30 hair roots from mane or tail. Test kits can be ordered free of charge. (order-form). If hair is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.
Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer. Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
