Acerca de la prueba

Prueba genética de 8 paneles para color de pelaje con resultados en 5 a 10 días hábiles.

Incluye 8 marcadores genéticos de color de pelaje:

Color base (2):

Agouti
Extensión

Diluciones (5):

Crema
Perla
Champán
Plata
Dun (D, nd1, nd2)

Despigmintación (1):

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

Nuestra prueba de Gris en paneles proporciona el número de copias del gen Gris (G/G, G/N o N/N).

Un Certificado Genético de Color – Genotipo del Pelaje y Predicción del Color del Pelaje en la Descendencia es proporcionado.

¿Por qué probar?

Las pruebas de ADN para pelajes pueden ser una herramienta importante para la selección, eliminación de enfermedades relacionadas con el pelaje y para mejorar tu criadero.

La determinación genética del color del pelaje permite identificar con precisión el genotipo del pelaje del caballo y ayuda a predecir la posible transmisión del color del pelaje a la descendencia.

Signos clínicos

How the eight results build a coat colour:

Agouti and Extension give the base coat colour: bay (A/- E/-), black (a/a E/-) or chestnut (-/- e/e)
Cream gives palomino, buckskin or smoky black with one copy, and cremello, perlino or smoky cream with two
Pearl shows with two copies, or with one Pearl and one Cream, and then looks much like a double Cream dilution
Champagne gives gold, amber and classic champagne
Silver lightens black pigment, including the mane and tail, so it shows on bay and black base coats
Dun lightens the body and adds a dorsal stripe and leg bars. An nd1 horse can have a dorsal stripe without the lightening
Grey acts on top of everything: the horse is born with its coat 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 link to disease. The panel does not diagnose disease; your veterinarian does.

Transmisión

A foal receives one allele of each gene from each parent, by chance. Cream and Pearl are two variants of the same gene (SLC45A2), so a horse can carry at most two of them in total. None of the eight genes is on a sex chromosome, so colts and fillies inherit them in the same way.

How each gene shows:

Agouti: a black base coat (a/a E/-) needs two a copies and at least one E
Extension: a chestnut base coat (-/- e/e) needs two e 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

Prevención

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

To be sure of a coat colour, look for a parent with two copies: a cremello (Cr/Cr) passes on Cream to 100% of its foals, and a G/G horse passes on Grey to 100% of its foals
To avoid a surprise coat 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

Coat colour should not be the only criterion for choosing a mating partner.

Preguntas frecuentes

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.
