Summerwind tests all our horses with Etalon Diagnostics. This includes Color, Genetic Diseases, and Traits like Curiosity, Gait and more. For more information on genetic research, testing and results, visit their website. https://www.etalondx.com/
Coat Color: Brasilia do Summerwind has no Red alleles and two Black, indicating her base coat color appears Black. One copy of the Dominant Agouti allele was also detected, it pushes/restricts Black out to points; legs, ear tips, etc. appearing Bay. As a result of the allele count in each of the following, she has a minimum 100% chance of passing Black and 50% Dominant Agouti to any offspring.
Allele Summary: Aa, EE, nd1/nd2, GG, CT (Mid-distance Type),
Her DNA was also tested on our discovery/validation platform for non-Dun Primitive Markings. Preliminary results indicate she is heterozygous for non-Dun Primitive Markings and may pass it to 50% of any offspring.
Traits: Brasilia do Summerwind has not tested positive for any recessive disease alleles on this panel.
- Trait Genetics Lordosis* – None
- Curiosity/Vigilance* – GG – Two Curiosity alleles detected; likely more curious than vigilant.
- Myostatin/Speed – CT (Mid-distance Type) – One Sprint and one Endurance allele detected; likely Mid-distance ability.
- Gait – No DMRT3 alleles detected. (Marcha batida Marchadors rarely show a DMRT3 allele)

Curiosity and Vigilance
Temperament is a complex trait influenced by multiple genetic and environmental factors. Individual components of temperament are potentially under different controls. Curiosity in the horse has been defined as an interest in novel objects and a willingness to approach them. Vigilance refers to the tendency of a horse to examine its surroundings. For this particular SNP, horses homozygous for the G allele (G/G) displayed both higher curiosity and lower vigilance scores, whereas horses with one or two A alleles (A/A and G/A) had lower curiosity and higher vigilance scores.
Research Confidence: Moderate confidence, findings replicated in multiple species

Gaited: Loss of Canter
Horses display a wide variation in locomotion, with “gaited” breeds displaying a range of unique footfall patterns at intermediate speeds. Even amongst the non-gaited (trotting) breeds, some individuals are capable of lateral movements. Also, while most horses will shift into the three beat canter at higher speeds, some horses are able to remain in their intermediate gaits (for example, harness racing breeds). The A/A genotype for this test is associated with the ability to remain in the intermediate gait at higher speeds.
Research Confidence: High confidence, findings reproduced in multiple studies
