À propos du test

Test génétique 8 marqueurs pour la couleur du pelage avec résultats en 5 à 10 jours ouvrables.

Comprend 8 marqueurs génétiques de couleur du pelage:

Couleur de base (2) :

Agouti
Extension

Dilutions (5) :

Crème
Perle
Champagne
Argent
Dun (D, nd1, nd2)

Décoloration (1) :

Gris* (G/G, G/N ou N/N)

Notre test Gris dans les panels fournit le nombre de copies du gène Gris (G/G, G/N ou N/N).

Un Certificat génétique de couleur – Génotype du pelage et prédiction de la couleur du pelage des descendants est fourni.

Pourquoi tester ?

Les tests ADN pour les robes peuvent être un outil important pour la sélection, l'élimination des maladies liées à la robe et l'amélioration de votre élevage.

La détermination génétique de la couleur de la robe permet une identification précise du génotype de la robe du cheval et aide à prédire la transmission potentielle de la couleur de la robe à la descendance.

Signes cliniques

How the eight results build a colour:

Extension and Agouti give the base: chestnut, bay or black
Cream gives palomino, buckskin or smoky black with one copy, and cremello, perlino or smoky cream with two
Pearl, when it shows, looks much like a double cream
Champagne gives gold, amber and classic champagne
Silver lightens black pigment and the mane and tail, so it shows on bays and blacks
Dun lightens the body and adds a dorsal stripe and leg bars. An nd1 horse can have a stripe without the lightening
Grey sits on top of everything: the horse is born with its colour and turns white with age

Health. Silver also causes an eye disorder, Multiple Congenital Ocular Anomalies (MCOA): horses with two copies have the severe form and horses with one copy the milder form. Grey horses develop skin melanomas far more often than other horses. The other genes in this panel have no known disease link. The panel does not diagnose disease; your veterinarian does.

Transmission

Each of the eight genes is inherited separately: a foal gets one copy of each gene from each parent, by chance. None is on a sex chromosome, so colts and fillies are the same.

How each gene shows:

Extension: chestnut needs two e copies
Agouti: black needs two a copies
Cream: one copy shows, two copies show more
Pearl: needs two copies, or one Pearl with one Cream
Champagne, Silver, Dun and Grey: one copy is enough

Prévention

With all eight genes known, you can plan matings for the colours you want, and against the ones you do not.

To be sure of a colour, look for a parent with two copies of it: a cremello always passes on Cream, and a horse with two Grey copies always passes on Grey
To avoid a surprise colour, check that neither parent is a hidden carrier
To avoid the severe Silver eye form, do not mate two Silver carriers
Have a horse that carries Silver examined by a veterinary eye specialist
For grey horses, ask your veterinarian to include skin checks for melanoma at routine visits

Colour should not be the only thing that decides a mating.

Questions fréquentes

What does this panel not detect?
White patterns (tobiano, frame overo, leopard complex, sabino, splashed white, dominant white), roan, Mushroom, the rarer Cream-gene dilutions Sunshine and Snowdrop, sooty and flaxen. Tobiano, frame overo, leopard complex and PATN1 have their own tests; the others need their own tests or have no test yet.

Should I order the panel or single tests?
The panel reads all eight genes and works out the colour from them together. If you only need one or two genes, the single tests cover them.

At what age can a horse be tested?
Any age. The result never changes, and foal coats are a poor guide to the adult colour, so testing early is worthwhile.

Breeds: Extension and Agouti vary in every breed. Cream was found in 25 of 28 breeds tested (Avila et al., 2022). Pearl occurs mainly in Iberian and stock-horse breeds. Champagne occurs in breeds such as the Miniature Horse, Tennessee Walking Horse and Missouri Fox Trotter. Grey has been found in at least 62 breeds and populations.
